What is the percentage of available chlorine in calcium hypochlorite?

Calcium hypochlorite is commonly used as a chlorine source for water disinfection due to its effectiveness and stability. The available chlorine percentage in calcium hypochlorite typically ranges between 65% and 70%. This high concentration of available chlorine makes it a potent disinfection option, especially in water treatment processes.

When calcium hypochlorite is added to water, it releases chlorine, which acts as a strong oxidizing agent to kill bacteria, viruses, and other pathogens. The specific range of 65% to 70% indicates that for every 100 grams of calcium hypochlorite, there are 65 to 70 grams of available chlorine that can be utilized for disinfection purposes.

Understanding the concentration of available chlorine is essential for operators and chemists working with water treatment, as it influences dosing rates, efficacy of disinfection, and overall water quality management. This knowledge helps ensure compliance with health and safety regulations in water treatment facilities.
