Question

Write the balanced equation when ammonia is dissolved in water.

Solution

$p K_{a}$ of water is lower than $N H_{3}$
Hence water is a stronger acid & donates the protons to $N H_{3}$ .
${N H_{3}}_{(a q)} + {H_{2} O}_{(l)} ⇌ {N H_{4}^{+}}_{(a q)} + O H_{(a q)}^{-}$
This reaction leads water to become the conjugate base $O H^{-}$ & $N H_{3}$ to become the conjugate acid $N H_{4}^{+}$ .
