Calcium hypochlorite is typically available in what concentration as a powder?

Calcium hypochlorite is commonly produced and sold as a powder with a typical concentration around 70%. This specific concentration is effective for disinfection and water treatment applications, making it a popular choice for use in swimming pools and drinking water systems. When calcium hypochlorite is in this concentration, it provides a sufficient level of available chlorine to sanitize water effectively, ensuring safety and compliance with health regulations.

Options with concentrations like 50%, 90%, or 30% do not reflect the standard formulations available on the market for calcium hypochlorite as a powder. Lower concentrations would not provide adequate sanitization capabilities, while concentrations that are too high could pose handling and safety risks. Thus, the 70% concentration balances effectiveness and safety for practical applications.
