Which one of the following is formed apart from sodium chloride when chlorine reacts with hot concentrated sodium hydroxide?
- $\mathrm{NaOCl}$
- $\mathrm{NaClO}_3$
- $\mathrm{NaClO}_2$
- $\mathrm{NaClO}_4$
Solution
When chlorine reacts with hot concentrated sodium hydroxide, sodium chloride, sodium chlorate and water are obtained.
$\mathrm{Cl}_2(g)+\underset{\text { (hot conc) }}{6 \mathrm{NaOH}} \stackrel{70^{\circ} \mathrm{C}}{\longrightarrow} 5 \mathrm{NaCl}$ $+\underset{\text { sodium chlorate }}{\mathrm{NaClO}_3}+3 \mathrm{H}_2 \mathrm{O}$
