Question
Why does $\mathrm{BeCl}_2$ react with water to give acidic solution? Give chemical reaction.
✓

Answer

$\mathrm{BeCl}_2$ is covalent, therefore, it gets hydrolysed to form $\mathrm{Be}(\mathrm{OH})_2$ and $\mathrm{HCl}, \mathrm{HCl}$, being strong acid, solution is acidic in nature.
$\text{BeCl}_2+2\text{H}_2\text{O}\xrightarrow{\ \ \ \\ \ \ \ }\text{Be(OH)}_2+2\text{HCl}$
