Question

Write the conjugate acids for the following Bronsted bases : $N{H}_2^{-},N{H}_3$ and $HCO{O}^{-}$.

Answer 1

Concept :-$Base+H^{+}\to conjugateacid$

$N{H}_2^{-}$ is a base, so it can accept a proton ($H^{+}$) and from conjugate acid.

$N{H}_2^{-}\left(base\right)+H^{+}\to N{H}_3\left(conjugateacid\right)$

$N{H}_3$ is a base so, it can accept a proton($H^{+}$) and form conjugate acid.

$N{H}_3\left(base\right)+H^{+}\to N{H}_4^{+}\left(conjugateacid\right)$

$HCO{O}^{-}$ is a base so, it can accept a proton($H^{+}$) and form conjugate acid.

$HCO{O}^{-}\left(base\right)+H^{+}\to HCOOH\left(conjugateacid\right)$
