Potassium Chromate Formula

Potassium chromate is an inorganic compound with the formula K2CrO4. It is a commonly used laboratory chemical. It is prepared by treating potassium dichromate with potassium hydroxide. Potassium chromate can be extracted from a natural mineral form known as the Tarapacaite. It occurs rarely and a very few localities on the Atacama desert is known to have Tarapacaite. In this short piece of article, learn about the potassium chromate formula along with its chemical structure, properties and uses.
