Getting
- in a chlorinator, by saturating water with gaseous chlorine, the resulting HClO decomposes in the light into O 2 and HCl
- formed in the process of producing caustic soda and chlorine by electrolysis on a mercury cathode
Application
It is used for disinfecting water in pools by the chlorination method, a very weak solution of chlorine in drinking water ensures its disinfection without causing great damage to health.
Chemical Properties
Strong oxidizing agent, primarily due to the formation of atomic oxygen at the time of release. It is one of the few substances that dissolve gold [1] .
Impact on human health
Chloramines (NH 2 Cl) irritate the skin and eyes [2] . Chlorinated water can intensify acne , and chlorine also dries the skin . [3] .
