Question

Complete the reaction. Sulphur dioxide $\mathrm{A}>$ Sodium sulphite.

Answer 1

1. Sodium sulphite is an inorganic salt with the chemical formula ${\mathrm{Na}}_2{\mathrm{SO}}_3$.
   It is a white, water-soluble, crystalline solid.
2. Sodium sulphite (${\mathrm{Na}}_2{\mathrm{SO}}_3$) can be prepared by sulphur dioxide (SO₂) by reaction it with sodium hydroxide (NaOH)
   The chemical equation for this reaction can be written as :
   ${\mathrm{SO}}_2\left(\mathrm{g}\right)+2\mathrm{NaOH}\left(\mathrm{aq}\right)\to {\mathrm{Na}}_2{\mathrm{SO}}_3\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{aq}\right)$
