When sulphur is boiled with $\mathrm{Na}_{2} \mathrm{SO}_{3}$ solution, the compound formed is
  1. Sodium sulphide
  2. Sodium sulphate
  3. Sodium persulphate
  4. Sodium thiosulphate

Solution

When sulphur is boiled with $\mathrm{Na}_{2} \mathrm{S}_{2} \mathrm{O}_{3}$ solution, the compound formed is sodium thiosulphate.
$8 \mathrm{Na}_{2} \mathrm{S}_{2} \mathrm{O}_{3}+\mathrm{S} ightarrow 8 \mathrm{Na}_{2} \mathrm{S}_{2} \mathrm{O}_{3}$
Hence, option (d) is correct. *
