Question

Equivalent mass for disproportionation reaction

Answer 1

Answer:

We all know that Equivalent weight=Molecular weightn-factor However consider a reaction like: BrX2+OHX−⟶BrX−+BrOX3X−+HX2O where oxidation numbers ..

Answer 2

So for oxidation, electron exchange=2*5=10. Dividing by total number of bromine molecules, i.e. 6, the Valency Factor of bromine molecule in the above disproportionation reaction is 10/6. If we look only reduction, then total electron exchange= 10*1=10.
