Silver permanganate is an inorganic compound with the chemical formula AgMnO4. This salt is a purple crystal adopting a monoclinic crystal system.[1] It decomposes when heated or mixed with water, and heating to high temperature may lead to explosion. The compound is used in gas masks.[citation needed]
Production
[edit]It can be produced through the reaction of silver nitrate and potassium permanganate:[2]
- AgNO3 + KMnO4 → AgMnO4 + KNO3
