POTASSIUM MANGANATE Usage And Synthesis

Chemical Properties

Potassium manganate, K2MnO4, green solid, soluble, permanent in alkali, formed by heating to high temperature manganese dioxide and potassium carbonate, and then extracting with water, and evaporating the solution. The first step in the preparation of potassium manganate and permanganate from pyrolusite.

Uses

It serves as an oxidizing agent.

Uses

A selective oxidizing agent.

Uses

Bleaching skins, fibers, oils; disinfectants; mordant (wool); batteries; photography; printing; source of oxygen (dyeing); water purification; oxi- dizing agent.

Hazard

Dangerous fire risk in contact with organic materials, strong oxidizing agent.
