SILVER PERMANGANATE Chemical Properties,Usage,Production

Chemical Properties

Violet, crystalline powder. contains 47.5% silver; decom- posed by alcohol; light-sensitive, use dark-colored bottles.

Uses

In gas masks.

Hazard

Dangerous explosion risk, may detonate if shocked or heated.

Purification Methods

The salt forms violet crystals which can be crystallised from hot H2O (soluble is 9g/L at 20o). Store it in the dark. This oxidising agent is decomposed by light. [Lux in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 1463 1963.]
