copper sulfate should be put into the swimming pool, which is about 1 cubic meters and 1 kilogram. The copper ion is blue, so it looks blue.

copper sulfate is added to the swimming pool for sterilization and disinfection.

Organic matter in swimming pools is easy to breed algae, and copper sulfate can inhibit the growth of algae. Moreover, copper ions dissolved in water can also combine with protein in bacterial cells, thus killing bacteria.

copper sulfate can be used to kill fungi, and most fungi can be killed with very low concentration of copper sulfate. It is reasonable to add a proper amount of copper sulfate to the swimming pool, which will not cause too much harm to the human body. The national standard stipulates that the copper sulfate added in swimming pools is .25 ~ .5 mg/L. Within this limited range, copper sulfate is safe for human body. If copper sulfate is used, its maximum dosage should not exceed 1. mg/L.

Extended information:

Used as analytical reagent, for example, it can be used to prepare the solution B for identifying reducing sugar and biuret reagent for protein in biology, but it is usually used now;

used as food-grade chelating agent and clarifying agent, used in preserved eggs and wine production process;

industrial field. Used to make other copper salts such as cuprous chloride, cuprous chloride, cuprous pyrophosphate, cuprous oxide, cupric acetate and cupric carbonate, and copper monoazo dyes such as reactive brilliant blue and reactive violet. The coating industry is used to produce antifouling paints for ship bottoms; Electroplating industry is used as the main salt and copper ion additive for all-bright acidic copper plating; Printing and dyeing industry is used as mordant and oxygen promoter for fine dyed cloth; Organic industry is used as a catalyst for the synthesis of perfume and dye intermediates and a polymerization inhibitor for methyl methacrylate. Anhydrous salt is used to catalyze transacetal reaction. Anhydrous salt reacts with potassium permanganate to generate an oxidant, which is used for the conversion of primary alcohol.
