Silver permanganate is an inorganic compound with the chemical formula AgMnO4. This salt is a purple crystal adopting 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[]
It can be produced through the reaction of silver nitrate and potassium permanganate:[2]
- AgNO
3 + KMnO
4 → AgMnO
4 + KNO
3
