Sodium bicarbonate (NaHCO? (sodium bicarbonate), commonly known as baking soda. White fine crystal, more insoluble in water than sodium carbonate. It is an industrial chemical with low toxicity. Solids above 50℃ begin to decompose gradually to produce sodium carbonate, carbon dioxide and water, and completely decompose at 440℃. Sodium bicarbonate is an acid salt formed by neutralization of strong alkali and weak acid, which is weakly alkaline when dissolved in water. This characteristic can make it a leavening agent in food production. Sodium carbonate will remain after the action of sodium bicarbonate, and excessive use will make the finished product have an alkaline taste.
Baking soda is also called baking soda in some places. Baking soda is solid. Monosalts are: normal salt, acidic salt and alkaline salt. Sodium bicarbonate is an acid salt produced by neutralization of strong alkali and weak acid, which is weakly alkaline when dissolved in water.
In the mass production of steamed bread, fried dough sticks and other foods, baking soda powder is often melted into noodles, which are decomposed into sodium carbonate, carbon dioxide and water after heating. Carbon dioxide and water vapor overflow, which can make the food more fluffy and sodium carbonate remains in the food. For example, alkali steamed bread, commonly known in the north, can be tasted by adding too much baking soda.
Question 2: What is baking soda and what is used to make sodium bicarbonate?
It is a weakly alkaline substance, which can inhibit the growth of fungi.
Originally used as a starter for bread making. ...
Advantages of baking soda:
1. Baking soda can remove odor and absorb moisture when put in the air. It can also be used as a cleaning agent after a long time.
Because baking soda was originally used to make bread leavening agent, it is edible, so you don't have to worry about chemical residue when you add it to clean water to wipe the floor.
3. If it does not cause any * * * to the skin, it can be used without gloves.
Magic cleaning function:
* Flow table: If the stainless steel desktop is foggy, you can use a sponge to dip a little baking soda and then gently scrub it to remove oil stains and scale, and then restore clean crystals.
* Cookware: When oil dirt accumulates on the gas stove shelf, soak it in hot water and baking soda for one night, and then scrub it, which will be very easy and effective. The ratio is 1 liter of hot water plus 1 tablespoon of baking soda.
* Pot: After the pot is burnt, wash it with baking soda, which can save the trouble of scrubbing. The method is to add clean water and 65,438+0 teaspoons of baking soda to a medium-sized pot for 8 minutes, boil over medium heat and turn off the heat. When the pan cools, drain the water and gently scrub it with a sponge. If there is burnt scale, add some baking soda to scrub it and you can clean it.
* Household appliances: Dirt on rice cookers and thermos bottles can be washed with clean water with dishcloth and baking soda, and then the surfaces of these small household appliances can be wiped to restore cleanliness.
* Glass table top: If there is oil stain on the glass table top, you can dip baking soda with a wet sponge, then gently wipe it, and then clean the traces of baking soda with clear water.
* Carpet: If the drink is accidentally knocked over or vomited, you can pour baking soda on it, so that baking soda can fully absorb moisture and taste, and then use a vacuum cleaner to clean it up, so that it can be clean and refreshing.
* Floor: When the floor is scribbled by children with oily crayons, clear water and baking soda can be mixed into a paste according to the ratio of 1: 2, and then evenly coated on the crayons, and can be removed after a little polishing.
Magic deodorizing effect:
* Refrigerator: Put baking soda in a small bowl or plate and put it directly into the refrigerator without a cover to remove the odor in the refrigerator. Replace/kloc-0 every 3-5 days, and the replaced baking soda can be used for kitchen cleaning.
* Chopboard: After the chopping board is cleaned, sprinkle baking soda evenly when it is slightly wet, let it stand for 1 hour and then wash it off to remove the odor. If your hands smell of fish or garlic, you can also wash your hands first. When there is still water, rub baking soda and wash it again.
* Closed container: clean the container first, then add hot water and baking soda, stir well, cover it and let it stand 1 night, then rinse it with clean water and dry it the next day, which can achieve the effect of removing odor.
* Confined space: the shoe cabinet or bathroom deodorizes normally. You can put baking soda in the cup for 7 minutes, without covering it, and put it directly in a place that is not easy to knock over. Replace it every week 1 time, and the replaced baking soda can be used for cleaning.
* Laundry: Before washing clothes with heavy sweat smell, you can sprinkle some baking soda on them to remove the sweat smell. When washing, put it directly into the washing machine with baking soda, which can also improve the cleaning and decontamination effect.
* shoes: put baking soda in old cotton socks, tie them with ropes and seal them, and then put them in shoes to deodorize and absorb moisture.
How to collect baking soda:
Baking soda can easily absorb moisture in the air, and it is best to put it away in a closed way when not in use, such as a sealed can or a chain bag or a milk powder can.
When it is used, you can put it away with a commercially available pepper can, but don't cover it. The hole in the pepper pot is convenient for sprinkling baking soda. If there is no pepper pot, you can also tie unwanted gauze curtains, mosquito nets and other mesh cloth to the general bottle mouth, which will be very convenient to pour out.
If you just want to prevent moisture and deodorize, you can put baking soda in the old cotton socks, seal them with ropes, and then use them at will. ...& gt& gt
Question 3: Smart housewives often use baking soda powder for different applications when necessary, and get good results. The domestic application of baking soda powder started from ordinary housewives. In the past twenty years, people's concern for the environment has shifted to the use of baking soda. Some people who don't want to have all kinds of organic solvents, harmful chemicals and suspected toxic chemical additives at home start to use baking soda because of its versatility, purity, safety and simplicity. The domestic use of baking soda powder has been increasing all over the world, because regardless of the user's motivation, baking soda powder is actually effective, cheap, convenient, safe, environmentally friendly and so on. Use baking soda, because baking soda can achieve the goal. Although the application of baking soda powder is developed by users themselves at home, it seems that there is no scientific basis. However, there are complete and reasonable scientific reasons why baking soda powder can be effective in different applications. Soda powder can relieve acidity and alkalinity. Most uses of baking soda powder are based on this basic chemical characteristic. Soda powder itself is a weak base, but it can buffer acid and alkali and keep neutral. Therefore, baking soda powder itself is both acidic and alkaline. In an acidic environment, baking soda becomes an alkaline chemical for neutralization. In alkaline environment, baking soda will become an acidic chemical for neutralization. This dual characteristic can explain many uses of baking soda powder. There is no doubt that the most important use of baking soda powder to relieve acid-base characteristics is brought when we are born. Bicarbonate naturally exists in our blood to maintain the delicate acid-base balance in our blood. Soda powder can remove dirt and debris. In terms of removing dirt and sundries, baking soda powder has three characteristics, which provide cleaning function, mild wear function and foaming function. The cleaning function of baking soda powder is that it is mild and weak if it is alkaline. Most dirt and grease contain fatty acids, which react with baking soda powder to form soap. The formed soap begins to remove other residual dirt and grease. Stronger alkali, such as lye or products made of lye, can produce stronger cleaning effect, but it is usually toxic and less safe than soda powder, which will damage the cleaned object and hurt people's hands. Paste sodium bicarbonate powder has slight abrasion. The dissolved part of baking soda powder can provide cleaning function for the dirt carried away by soft undissolved baking soda powder crystals. These baking soda crystals are softer than any surface and are easily broken when used. In fact, their function exceeds wear and can be polished. Soda powder will not scratch the surface of most household items, but it can be put into soap and washing powder to enhance its cleaning ability. Soda powder can not only react with dirt to form soap, but also generate bubbles to make dirt float on the surface. All you need is baking soda, water and common kitchen acids, such as vinegar. Soda powder's unique combined cleaning effect makes it a safe cleaner choice in the family, which has almost every cleaning function, from dirty kitchen sink to moldy shower curtain to teeth. Soda can deodorize odor, which is formed by some odorous gases in the air. There are two commonly used deodorants, one is aromatic, which covers the smell like perfume, and the other is absorbent, which absorbs the smell, such as activated carbon. Aromatherapy can't remove the odor, just cover it with fragrance. The adsorbent will fail if it is saturated for a long time, so it can't absorb odor. Sometimes the adsorbed odor will be discharged back into the air by the adsorbent, so the adsorbent that usually fails becomes the source of odor. Soda powder is an adsorbent, but it can not only adsorb odor, but also neutralize odor, so even if the adsorption function fails, the adsorbed odor will not become the odor source again. Many odorous gases are strong acids or alkalis. The deodorization function of baking soda powder is to absorb odor, and then neutralize acidic or alkaline odorous gas through chemical reaction, so as to transform it into odorless chemicals. The best place to use baking soda as deodorant is in a closed and humid space, such as refrigerator, car or closet. The deodorization efficiency of soda powder depends on the odor concentration in the air and the contact time. The longer the contact time, the more odor will be removed until it reaches saturation. In the refrigerator, an open box of baking soda is valid for three months. Dissolved baking soda powder can also be used as a deodorant. The way of deodorization is the same as that in the air, and the smell is neutralized in the reaction. For example, gargling with baking soda solution can eliminate the garlic smell in your mouth. Soda powder can put out fires. Soda powder will decompose into sodium carbonate and carbon dioxide at high temperature. Can be used to extinguish the fire source of flammable liquids, such as oil, gasoline, fuel oil and solvents. It can also be used to extinguish electrical equipment and power ... >>
Question 4: What's the difference between baking soda and baking soda? Soda is transliteration, and its chemical formula is Na2CO3. It has many names, the scientific name is sodium carbonate, the common name is soda, and it is also called soda ash or baking soda powder. Crystal water is called hydrated sodium carbonate, and sodium carbonate monohydrate (Na2CO3? H2O), sodium carbonate heptahydrate (Na2CO3? 7H2O) and sodium carbonate decahydrate (Na2CO3? 10H2O)。 Sodium carbonate decahydrate is also called alkali washing, alkali washing or crystallization alkali. Anhydrous sodium carbonate is white powder or fine particles, easily soluble in water, and its aqueous solution is alkaline. It has strong hygroscopicity and can absorb moisture in the air to form lumps. Sodium carbonate decahydrate is a colorless crystal. If left in the air at room temperature, it will lose its crystal water and become sodium carbonate monohydrate. When heated, both sodium carbonate decahydrate and sodium carbonate monohydrate will become anhydrous sodium carbonate. Sodium carbonate is very stable and is not easy to decompose when heated. In case of acid, carbon dioxide can be released: Na2CO3+2HCl = = 2NaCl+H2O+CO2 = sodium carbonate solution can also absorb carbon dioxide to form sodium bicarbonate: Na2CO3+H2O+CO2 = = = 2NahCo3. Among the three kinds of soft drinks, sodium carbonate is the most widely used. It is a very important chemical product and an important raw material for glass, soap, textile, paper making, leather making and other industries. It is also used in metallurgical industry and water purification. It can also be used to make other sodium compounds. As early as the eighteenth century, it was listed as one of the basic chemical raw materials-diacid dibasic with sulfuric acid, hydrochloric acid, nitric acid and caustic soda. In daily life, soda also has many uses. For example, it can be directly used as a detergent. Adding soda when steaming steamed bread can neutralize the acidic substances produced in the fermentation process. Baking soda (also known as sodium bicarbonate) is a white crystalline powder, which is soluble in water. It is a weak base, which can neutralize gastric acid and dissolve mucus. After absorption, it can increase the alkali reserve and have certain expectorant effect. In veterinary clinic, it is mainly used to treat catarrhal inflammation of gastrointestinal tract, septicemia and severe diarrhea, extensive burns, neutralizing gastric acid and alkalizing urine. Adding baking soda to livestock and poultry feed can effectively improve the digestibility of livestock and poultry feed, accelerate the utilization of nutrients and excretion of harmful substances, and improve the weight gain speed of livestock and poultry; It can keep the resistance and immunity of livestock and poultry in the best state all the time, improve the anti-stress ability of livestock and poultry, and play a positive role in preventing livestock and poultry diseases and ensuring their healthy growth. Baking soda (edible sodium bicarbonate) is an edible alkali! When making steamed bread or bread, you should use alkali and dissolve it in hot water, but you should master the dosage. Eating too much steamed bread will turn black and make it bitter. If you eat less steamed bread, it will sour. I suggest you add it bit by bit, as much as possible. This should be its most common usage. There are also some small uses, such as teacups, teapots or other utensils that often drink tea. There are so many tea stains that it is difficult to brush them off. It is easy to soak them in alkaline water (warm water) and then brush them again. Of course, you can also send things with a lot of oil stains. If the detergent at home suddenly runs out, it can be used to temporarily replace the following. Pay attention to washing them clean. It is said that it was used to wash face and hair when there was no soap and shampoo before. But washing tea stains is really convenient. Highly recommended!
Question 5: What is baking soda powder and where can I buy it? There will be one in the supermarket! I use it to brush my teeth.
Question 6: What's the difference between baking soda, baking soda and starch? Baking soda is used to make dough and neutralize acid. Now you don't need yeast, you can use soaked beans. Soda is toxic as an industrial raw material, but it can be used to wash toilets. Starch, including potatoes, corn and mung beans, has different functions. Something fried with potato flour.
Question 7: Is baking soda the same as flour? Soda powder is also called edible alkali (powder) in some places Baking soda is solid, round, white and easily soluble in water. Baking soda is also called calcium bicarbonate. Generally used as puffing agent can make food crisp and delicious. Used as a starter for food processing, a producer of carbon dioxide in soft drinks and cold drinks, and a preservative for butter.
Flour refers to wheat flour, that is, flour ground from wheat.
Question 8: What is baking soda in the kitchen? Sodium bicarbonate, commonly known as "baking soda", "sufu powder" and "Cao Chong", is white and fine-grained, and its solubility in water is less than that of sodium carbonate. Solids above 50℃ begin to decompose gradually to produce sodium carbonate, carbon dioxide and water, and completely decompose at 270℃. Sodium bicarbonate is an acid salt formed by neutralization of strong alkali and weak acid, which is weakly alkaline when dissolved in water.
