Chemical Properties of Potassium Permanganate Potassium permanganate is soluble in acetone, water, pyridine, methanol and acetic acid. It is also readily soluble in inorganic solvents. It has a rich purple colour in concentrated solution and pink colour in dilute solution. It is not combustible but supports the combustion of other substances.

Potassium manganate is the inorganic compound with the formula K2MnO4. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate ( KMnO4 ), a common chemical. [1] Occasionally, potassium manganate and potassium per manganate are confused, but these compounds's properties are distinct.

The number of moles of K M n O 4 that will be needed to react completely with one mole of ferrous oxalate in acidic solution is:

There are mostly two equations to prepare KMnO4. The equation to prepare KMnO4 with the use of HCl is given below – 2K2MnO4 + 4HCl → 2KMnO4 + H2O + MnO2 + 4KCl Preparation with H2SO4 The equation used in the preparation of KMnO 4 with the use of H 2 SO 4 is given below, 3K2MnO4 + 2H2SO4 → 2KMnO4 + 2H2O + MnO2 + 2K2SO4

HCl and HNO3 are not used in the titration of Mohr’s salt in place of sulfuric acid because: HCl is a mild reducing agent and it reacts with some of the indicator that is KMnO4 solution so the final value of the indicator used come to be more than the actual value disturbing the experiment.

Which is better oxidising agent KMnO4 or K2Cr2O7? The KMnO4 is stronger oxidizing agent than k2Cr2O7 because due to its higher reduction potential since as we know that the compound having higher reduction potential behaves as best oxidizing agent . Here reduction potential value of KMnO4 is +1.52V and K2Cr2O7 has +1.33V .
