Sodium permanganate is a chemical compound from the group of sodium compounds and permanganates .

Extraction and presentation

Sodium permanganate can be obtained by reacting manganese dioxide with sodium hypochlorite .

properties

Sodium permanganate is a purple, odorless, oxidizing solid that is soluble in water. It decomposes when heated, producing oxygen .

use

Due to its high solubility, its aqueous solutions are used as an etchant for printed circuit boards.

In the V2 rocket it was used for propulsion through the catalytic decomposition of highly concentrated hydrogen peroxide .

Sodium permanganate is also used in the industrial production of cocaine . That is why the US Drug Enforcement Agency (DEA) has restricted sales since 2006, which led to the price of cocaine doubling.
