Bleaching powder itself has certain hazards, such as burning and explosion when exposed to high temperature, water, acid or grease, and increasing its danger when exposed to metal powder. In addition, bleach powder is also a combustion aid, which can promote the combustion of surrounding combustibles and cause fires. Moreover, when bleach powder burns with water, it emits a suffocating odor of chlorine gas, which can cause toxicity to the human body through the upper respiratory tract and skin mucosa. In recent years, such accidents have been common, not only causing huge property losses, but also posing a threat to people's lives.
Active ingredient: Ca (ClO) ₂ - calcium hypochlorite
Bleaching powder is prone to failure when exposed to air: Ca (ClO) ₂+H ₂ O+CO ₂=CaCO Å↓+2HClO
Ionization in water: Ca (ClO) ₂=Ca2++2ClO-
Hydrolysis in water: Ca (ClO) ₂+2H ₂ O
