What is a common form of calcium hypochlorite?

Granular calcium hypochlorite is widely recognized as a common form of this compound used in water treatment. It is typically manufactured as a white granular substance that is highly effective for disinfection applications. This form allows for straightforward handling and application in various settings, including swimming pools and municipal water supply systems.

In terms of its chemical properties, granular calcium hypochlorite releases chlorine when dissolved in water, making it a potent oxidizing agent used to eliminate bacteria and other pathogens. This format is advantageous for long-term storage since it is relatively stable and can be stored safely without deterioration.

The other options represent different forms or types of chlorine products but do not directly correspond to calcium hypochlorite. For instance, liquid chlorine is a different compound, typically sodium hypochlorite, and while powdered chlorine refers to another form available in the market, it is distinct from granular calcium hypochlorite. Chlorine tablets are also popular but are usually compressed forms of chlorine and not specifically calcium hypochlorite.
