Manganese (VI) has ability to disproportionate in acidic solution. The difference in oxidation states of two ions it forms in acidic solution is ____________.

Step-by-Step Verified Solution

Manganese (VI)(\mathrm{VI}) disproportionates in acidic medium as

3MnO42−+4H+⟶2MnO4−+MnO2+2H2O3 \mathrm{MnO}_{4}^{2-}+4 \mathrm{H}^{+} \longrightarrow 2 \mathrm{MnO}_{4}^{-}+\mathrm{MnO}_{2}+2 \mathrm{H}_{2} \mathrm{O}

The difference in oxidation states of Mn\mathrm{Mn} in the products formed =7−4=3=7-4=3
