What is KMnO4 and How is it Used?
The chemical name for the compound is potassium permanganate. The molar mass is 158.034g/mol .It is an Oxidizing agent with disinfectant properties. It is also Called as permangante of potash Or Condy’s crystal. When alkali metal hydroxide (KOH) react with MnO4 in presence of oxidizing agent like KNO3 or in oxygen it produces compound KMnO4.It does not occur in nature but it is produced in industry from magnesium dioxide.It is purple to magenta crystalline solid, odourless. It get dissolved in acetic acid, acetone, water and methanol. It is used in treatment of skin disease such as fungal infection in foot. It is non -combustible but enhance the combustion of other substance. Inhaling potassium permanganate can irritate the lung causing cough or problem in breathing.
Uses:-
1)metal processing
2) chemical manufacture
3) wastewater treatment
4) pesticides
5) printing fabrics.
