An acidified manganate solution undergoes disproportionation...

An acidified manganate solution undergoes disproportionation reaction. The spin-only magnetic moment value of the product having manganese in higher oxidation state is____B.M. (Nearest integer)

Correct answer

0

Step-by-step solution

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

As we can see in this reaction oxidised product of reaction is MnO4−{MnO}_{4}^{-} which has no unpaired electrons. So, magnetic moment will be zero.

Mn=Mn = no. of unpaired electrons is '00'

μ=0B.M\mu = 0B . M
