Generally ranging from 2500 yuan/ton to 4500 yuan/ton, the specific price is determined by raw material price, sodium hydroxide content, sodium hydroxide form, manufacturers and other factors. Soda, commonly known as sodium hydroxide, is an important and commonly used chemical raw material.
Expand knowledge: where can I buy caustic soda and how to tell the truth from the false?
Where can I buy caustic soda?
If you need to purchase caustic soda in large quantities in general industrial production, it is recommended to contact the manufacturer directly for wholesale order. If it is purchased in small quantities, such as for experiments or home sewage, it can be purchased through the following channels:
1. Reagent-grade and industrial-grade sodium hydroxide can be bought in electroplating materials stores.
2. Reagent-grade sodium hydroxide can be bought in chemical reagent stores.
3. Industrial-grade sodium hydroxide can be bought in chemical raw materials stores, and some will also have reagent-grade supply.
How to distinguish the authenticity of caustic soda;
1, judging from the appearance
Pure caustic soda generally refers to sodium hydroxide with a content above 96%. This caustic soda is a translucent crystal between white and transparent. If you think that the bought caustic soda is the wrong color, or contains impurities of black or other colors, it proves that the purity is not high, or it is fake. Secondly, caustic soda tablets are very brittle, and they will crack and break instantly when pressed hard. Caustic soda water feels smooth and completely transparent. If there are insoluble impurities, they are also impure.
2. Look at the temperature when dissolving.
The process of dissolving caustic soda in water will give off a lot of heat. You can put caustic soda into water and touch the outer wall of the diluent container with your hands to feel the temperature. Generally, about 2 ounces of caustic soda is dissolved in 5 kilograms of water, and the temperature will be above 50℃ after 10 second. Low-content caustic soda or fake caustic soda will not generate heat or generate less heat. It should be noted that never touch caustic soda tablets or caustic soda water directly with your hands. They are extremely corrosive and will harm your skin.
Step 3 look at the price
The price of caustic soda is generally affected by many factors, including high and low. When the market demand is large, the price will be higher. Everyone should pay attention to distinguish the price, production cost plus transportation cost, distribution price increase and other expenses when buying. It's usually more than two yuan a catty. If it is too cheap, it is necessary to consider whether it is a fake or the caustic soda content is not up to standard.
