Hydrazine reacts with $KIO_{3}$ in presence of HCl as $N_{2} H_{4}^{+} + 2 H^{+} + Cl^{-} \to ICl + N_{2} + 3 H_{2} O$ The equivalent masses of $N_{2} H_{4}$ and $KIO_{3}$ respectively are :

Options:

Answer:

Solution:

For N₂H₄: N oxidation state changes from -2 to 0 (4e⁻ change). Equivalent mass = M/4 = 32/4 = 8.

For KIO₃: I oxidation state changes from +5 to +1 (4e⁻ change). Equivalent mass = M/4 = 214/4 = 53.5.
