Equivalent mass of$\mathrm{K}\mathrm{M}\mathrm{n}{\mathrm{O}}_4$in acidic, basic and neutral medium are 31.6, 158 and 52.6. The ratio will be 3 : 15 : 5.
n-factor of$\mathrm{K}\mathrm{M}\mathrm{n}{\mathrm{O}}_4$in acidic, basic and neutral medium are 5, 1 and 3 respectively.
Acid medium : Basic medium : Neutral medium
${\mathrm{E}}_{\mathrm{w}}=\frac{{\mathrm{M}}_{\mathrm{w}}}{5}=\frac{158}{5}$:${\mathrm{E}}_{\mathrm{w}}=\frac{{\mathrm{M}}_{\mathrm{w}}}{1}=\frac{158}{1}=158$:${\mathrm{E}}_{\mathrm{w}}=\frac{{\mathrm{M}}_{\mathrm{w}}}{3}=\frac{158}{3}$
3 : 15 : 5
