The conjugate base of hydrazoic acid is:

The conjugate base of hydrazoic acid is:
  1. $\mathrm{N}^{-3}$
  2. $\mathrm{N}_3^{-}$
  3. $\mathrm{N}_2^{-}$
  4. $\mathrm{HN}_3^{-}$

Solution

$\mathrm{N}_3 \mathrm{H} \rightleftharpoons \mathrm{N}_3^{-}+\mathrm{H}^{+}$ Hydrazoic acid i.e, conjugate base of hydrazoic acid is $\mathrm{N}_3^{-}$.
