What is the chemical name for dry chlorine?

The chemical name for dry chlorine is indeed calcium hypochlorite. This compound is widely used in swimming pools as a disinfecting agent because it effectively releases chlorine when dissolved in water, which helps in killing harmful microorganisms and maintaining water quality. Calcium hypochlorite is commonly found in a granular or tablet form, making it convenient for pool operators to handle and apply.

In contrast, sodium hypochlorite refers to a liquid form of chlorine commonly used for disinfection but lacks the solid form associated with dry chlorine. Sodium chloride is table salt and is not related to chlorine disinfection, while sodium bicarbonate, often used as a pH buffer in pools, also does not serve as a chlorine source. Understanding these distinctions is crucial for proper pool management and ensuring safe swimming conditions.
