What is K2MnO4? Important knowledge about K2MnO4.

1. Definition of K₂MnO₄

K₂MnO₄, also known as Potassium Manganate, in English is Potassium manganate. It is a salt of potassium and manganate. K₂MnO₄ consists of two potassium atoms, one manganese atom, and four oxygen atoms. The total atomic mass of K₂MnO₄ is 197.13 g/mol. In K₂MnO₄, manganese (+6) and potassium (+1) form the manganate ion (MnO₄ -2) and the potassium ion (K+).
