Potassium Permanganate

Potassium permanganate is an inorganic compound and has a strong oxidizing agent. The potassium has a positive charge(cation) and the permanganate is a negative charge(anions). This chemical compound is dissolves in water. yearly it was produced the 20 to 30 thousand tonnes from the worldwide.  The systematic IUPAC name is known as potassium permanganate . The chemical or molecular formula of potassium permanganate is KMnO4. It is also known as the hypermangan or condys crystals.

Structural Formula

This is the structural formula of the potassium permanganate:

Potassium Permanganate

Chemical Formula

The chemical formula of the Potassium permanganate is KMnO4.

Preparation Method

When the potassium hydroxide is along with the water is reacted with the manganese oxide. It gives the water as the byproduct. By electrolytic oxidation the manganete is converted into the permanganate. Because it is an alkaline metal. The acid can be induced in the disproportional reactions. Under the acidic conditions it is oxidized by the chlorine to get the permanganate and the potassium chloride is the byproduct.
