Calcium hypochlorite is an inorganic compound with formula Ca(ClO)2.
As a mixture with lime and calcium chloride, it is marketed as chlorine
powder or bleach powder for water treatment and as
a bleaching agent.
Detailed description
This
compound is relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach).[2] It is a
white solid, although commercial samples appear yellow. It strongly smells
of chlorine, owing to its
slow decomposition in moist air. It is not highly soluble in water and is more
preferably used in soft to
medium-hard water. It has two forms: dry and hydrated.
Uses
Sanitation
Calcium hypochlorite is commonly used to sanitize public
swimming pools and disinfect drinking water. Generally the
commercial substance is sold with a purity of a 68% (with other additives and
contaminants varying based upon the product's intended purpose). For instance
as a swimming pool chemical it is often mixed with cyanuric acid stabilizers
and anti-scaling agents (in order to reduce the loss of chlorine from ultraviolet radiation and
to prevent calcium hardening).
Calcium hypochlorite is also used in kitchens to disinfectsurfaces and
equipment.[3] Other common
uses include bathroom cleansers,
household disinfectant sprays, algaecides, herbicides, and laundry detergents.
Organic chemistry
Calcium hypochlorite is a general oxidizing agent and therefore
finds some use in organic chemistry.[4] For instance
the compound is used to cleave glycols, α-hydroxy carboxylic acids and keto acids to yield
fragmented aldehydes or carboxylic acids.[5] Calcium
hypochlorite can also be used in the haloform reaction to
manufacture chloroform.[6]
