【Summary】Main composition is calcium hypochlorite bleaching powder, calcium hypochlorite with CO2 and water vapor in the air to generate hypochlorous acid and calcium carbonate (the reaction of bleaching powder is in fact the work), if you don't use will be photolysis (long dark also reacts to) produce the oxygen and hydrogen chloride gas (or hydrochloric acid),

Information

Main composition is calcium hypochlorite bleaching powder, calcium hypochlorite with CO2 and water vapor in the air to generate hypochlorous acid and calcium carbonate (the reaction of bleaching powder is in fact the work), if you don't use will be photolysis (long dark also reacts to) produce the oxygen and hydrogen chloride gas (or hydrochloric acid), then failed

The main components of bleaching powder are calcium hypochlorite and calcium chloride, the active component is calcium hypochlorite. The bleaching principle of bleaching powder is the reaction of calcium hypochlorite and acid to produce bleach material hypochlorite:

Ca(ClO)2＋2HCl(rare)＝CaCl2＋2HClO 

Ca(ClO)2＋CO2＋H2O＝CaCO3↓＋2HClO 

Hypochlorous acid is a weak acid that can oxidize pigments and thus achieve bleaching purposes.

The effective component of bleaching powder is calcium hypochlorite, and the hypochlorite acid generated by acid has bleaching effect

Failure is hypochlorite calcium acid acid generated hypochlorite, and decomposition.

Ca(ClO)2+CO2+H2O=CaCO3+HClO(Strong acid to weak acid)
2Hclo=2Hcl+O2↑

Without hypochlorite, of course, it's no longer effective.

Disinfectants are the most commonly used drugs in aquaculture to eliminate or kill pathogenic microorganisms and other harmful microorganisms in the external environment. According to the chemical properties can be divided into aldehyde disinfectants, base disinfectants, acid disinfectants, salt disinfectants, halogen disinfectants, dyes, oxidants, heavy metal disinfectants and other eight categories. There are many kinds of aquaculture animals in China, and the toxicity of different disinfectants to aquatic animals varies greatly. Improper use of disinfectants is easy to cause poisoning and death of fish and shrimp. However, there is still a lack of standard data on the toxicity of disinfectants in China.

In aquaculture, bleaching powder is mainly used in pond disinfection and prevention and treatment of bacterial fish disease. 1. Pond cleaning and disinfection. The general dosage is 20-30 grams per cubic meter of water. Dissolve the bleach powder with water first, and then sprinkle the whole pool, which can kill aquatic insects, frog eggs, fish, spiral snails and various fish disease pathogens in the water body....
