Hydrazine reacts with `KIO_(3)` in presence of `HCl` as `:`
`N_(2)H_(4)+IO_(3)^(-)+2H^(+)+Cl^(-) rarrICI+N_(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)`
