Hydrazine reacts with `KIO_3` in presence of `HCI` as `N_2H_4+IO_3^- +2H^+ + CI^- rarr ICI + N_2+3N_2 +3H_2 O` The equivalent masses of `N_2 H_4 and KIO_3` respectively are :

Options

A. 8 and `53.5`
B. 16 and `53.5`
C. 8 and `35.6`
D. 8 and 87

Answer

1

Explanation

Oxidation number of `N` in `N_(2)H_(4)` is `-2` which change `s` to `0` in `N_(2)`.
Hence , equivalent mass of `N_(2)H_(4)=("Molar mass")/(2xx2)`
Oxidation number of iodine changes from `+5` to `+1` in `ICI`
Hence, equivalent mass of `IO_(3)=("Molar mass")/(4)`
