Manganese (VI) has ability to disproportionate in acidic solution....

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

Correct answer

3

Step-by-step solution

In acidic solution Mn(VI) become unstable relative to Mn(VII) and Mn(IV)

3MnO42−+4H+→2MnO4−+MnO2+2H2O3{MnO}_{4}^{2 -} + 4{H}^{+} \to 2{MnO}_{4}^{-} + {MnO}_{2} + 2{H}_{2}O
So difference in oxidation state of product ions of Mn is = 3
