Question
What happens when
  1. Calcium phosphide is hydrolysed
  2. Ammonia reacts with water
✓

Answer

  1. Phosphine is formed.
$\text{Ca}_3\text{P}_2+6\text{H}_2\text{O}\xrightarrow{\ \ \ \ \ \ }3\text{Ca}(\text{OH})_2+2\text{PH}_3$
  1. $\mathrm{NH}^{+}{}_4$ and $\mathrm{OH}^{-}$are formed.
$\text{NH}_3+\text{H}_2\text{O}\xrightarrow{\ \ \ \ \ \ \ }\text{NH}_4^++\text{OH}^-$
