Q.
Match incorrect equivalent mass of reactant in following column ? ($M$ = molar mass of reactant):-
Column I
Column II
1
$FeS_2 \to Fe^{3+} + SO_3$
$\frac{M}{15}$
2
$P_2H_4 \to P_4H_2 + PH_3$
$\frac{5M}{6}$
3
$2Mn^{+7} \to Mn^{2+} + Mn^{+6}$
$\frac{M}{3}$
4
$Ba(MnO_4)_2 \xrightarrow{H^+} Mn^{2+}$
$\frac{M}{5}$
| Column I | Column II | |
|---|---|---|
| 1 | $FeS_2 \to Fe^{3+} + SO_3$ | $\frac{M}{15}$ |
| 2 | $P_2H_4 \to P_4H_2 + PH_3$ | $\frac{5M}{6}$ |
| 3 | $2Mn^{+7} \to Mn^{2+} + Mn^{+6}$ | $\frac{M}{3}$ |
| 4 | $Ba(MnO_4)_2 \xrightarrow{H^+} Mn^{2+}$ | $\frac{M}{5}$ |
