Calcium hypochlorite contains __________% available chlorine.

Calcium hypochlorite is a chemical compound often used in water treatment and disinfection processes due to its ability to release chlorine. The percentage of available chlorine refers to the amount of chlorine that is actively available to disinfect water.

In the case of calcium hypochlorite, it contains approximately 65% available chlorine. This means that when calcium hypochlorite is used, 65% of its weight contributes to the effective chlorine action necessary for disinfection. This higher percentage makes calcium hypochlorite a potent option for chlorination in wastewater treatment processes.

Understanding the concentration of available chlorine in different compounds is crucial for determining the appropriate dosing and ensuring effective treatment while maintaining safety and compliance with regulations in wastewater management.
