WebDetermine the oxidation states of all the atoms in potassium permanganate, KMnO4. ElementOxidation State Mn Question4 10 pts Determine the oxidation states of all the atoms in sodium oxalate, Na2C204 Element Oxidation State Na This problem has been solved! Potassium permanganate is produced industrially from manganese dioxide, which also occurs as the mineral pyrolusite. In 2000, worldwide production was estimated at 30,000 tonnes. The MnO2 is fused with potassium hydroxide and heated in air or with another source of oxygen, like potassium nitrate or potassium chlorate. This process gives potassium manganate: 2 MnO2 + 4 KOH + O2 → 2 K2MnO4 + 2 H2O
