Sodium permanganate

Sodium permanganate is a chemical compound. Its chemical formula is NaMnO4. It contains sodium and permanganate ions.

Properties
It is a purple-black crystalline solid. It can dissolve in water to make a bright pink solution. It dissolves in water more than potassium permanganate. It is more expensive than potassium permanganate. It also absorbs water from the air. It is a strong oxidizing agent. 

Preparation
It cannot be made in the way that potassium permanganate is made because sodium manganate is not made. It can be made by reacting pure manganese(IV) oxide with sodium hypochlorite. It can also be made by reacting potassium permanganate with certain sodium compounds.

Uses
It can be used to make circuit boards.

Safety
Permanganates are toxic. They are also strong oxidizing agents and should be kept away from things that can burn.
