What is the chemical name of liquid chlorine?

The chemical name for liquid chlorine is Sodium Hypochlorite, which is a commonly used disinfectant in swimming pools. It is produced by dissolving chlorine gas in a sodium hydroxide solution. Sodium Hypochlorite is widely favored for its effectiveness in killing bacteria and controlling algae in pool water, making it a popular choice among pool operators for maintaining clean and safe swimming environments.

In contrast, Calcium Hypochlorite (another disinfectant) is usually found in solid or granular form rather than as a liquid. Sodium Chloride, commonly known as table salt, is not a disinfectant and does not serve the same purpose in pool maintenance. Sodium Bicarbonate, or baking soda, is often used to raise alkalinity in pool water but does not have disinfectant properties. Hence, the context around these choices highlights why Sodium Hypochlorite is the accurate answer.
