Question
Chlorination of calcium hydroxide produces bleaching powder. Write its chemical equation.
✓

Answer

Bleaching powder is obtained by passing $\mathrm{Cl}_2$ into $\mathrm{Ca}(\mathrm{OH})_2$. Though bleaching powder is often written as $\mathrm{Ca}(\mathrm{OCl})_2$, it is actually a mixture of $\mathrm{Ca}(\mathrm{OH})_2 ; \mathrm{CaCl}_2$ along with $\mathrm{Ca}(\mathrm{OCl})_2$.
$3\text{Ca(OH)}_2+2\text{Cl}_2\xrightarrow{ \ \ \ \ \ \ \ \ \ \ }\\ \text{Ca(OCl)}_2\cdot\text{Ca(OH)}_2\cdot\text{CaCl}_2\cdot2\text{H}_2\text{O}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{Bleaching powder}$
