Question

Hydrazine reacts with KIO₃ in presence of HCl as

N₂H₄ + $IO_{3}^{-}$ + 2H⁺ + Cl^– ®ICl + N₂ + 3H₂O

The equivalent masses of N₂H₄ and KIO₃ respectively are:**[**KIO₃ = 214 ]

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

Answer 1

Answer: (A)

8 and 53.5

Answer 2

N₂H₄ ® N₂ n factor = 4

\ Eq. wt = $\frac{32}{4} = 8$

$\overset{+ 5}{I}$O₃^– ®$\overset{+ 1}{I}$ n factor = 4

\Eq. wt = $\frac{214}{4} = 53.4$
