Lithium hypochlorite , LiClO, is a white powder and the hypochlorite of lithium .

Extraction and presentation

Treatment of a lithium hydroxide solution with dichloromonoxide allows the salt to be extracted:

${\displaystyle {\ce {2 LiOH + Cl2O -> 2 LiClO + H2O}}}$

This reaction is not complete and gets weaker over time.

properties

Dry lithium hypochlorite reacts with chlorine . This produces lithium chloride and dichloromonoxide:

${\displaystyle {\ce {LiClO + Cl2 -> LiCl + Cl2O}}}$

When the salt is moistened, lithium chlorate is formed instead .

use

Lithium hypochlorite is used to disinfect swimming pools.

safety instructions

Caution should be exercised when working with lithium hypochlorite. It can be harmful to health through absorption through the skin and cause corrosion. It is extremely damaging to tissue in the upper respiratory tract and on the mucous membranes.

Symptoms such as cough, headache or shortness of breath may occur after exposure.
