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)

Step-by-step solution

3 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 MnO 4 - which has no unpaired electrons. So, magnetic moment will be zero. Mn = no. of unpaired electrons is ' 0 ' μ = 0   B . M
