What is pottasium permanganate?
Potassium permanganate is a chemical compound with formula KMnO4
. It is violet-black in colour. It consists of Potassium, manganese
and oxygen atoms. It is an oxidizing agent as here manganese is in
+7 oxidation state. It is very soluble in water giving purple
solutions. It can oxidize aldehydes to carboxylic acids, and
secondary alcohols into ketones. It dissolves in many acids to give
Manganese(II) salts. It is also reduced in strong alkaline
conditions to Manganate (MnO4-2) ions, which are greenish in
colour. It is a strong oxidizer, so it may cause many organic
materials to catch fire on its contact. It can stain the skin, to
brown colour. It has a horrible taste, and it will also stain the
tongue and damage some taste buds. It also has antiseptic
