Question

Fill in the blanks: What happens when a solution of sodium sulphate is added to barium chloride______

Answer 1

Explanation:

1. When Sodium Sulphate is reacted with Barium Chloride, there is a formation of Sodium Chloride salt and Barium Sulphate precipitate.
2. It is a precipitation reaction.

$\underset{\mathrm{Sodium}\mathrm{sulphate}}{{\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}+\underset{\mathrm{Barium}\mathrm{chloride}}{{\mathrm{BaCl}}_2\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{chloride}}{2\mathrm{NaCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{Barium}\mathrm{sulphate}}{{\mathrm{BaSO}}_4\left(\mathrm{s}\right)(\downarrow )}$

Hence, When a solution of sodium sulphate is added to barium chloride there is the formation of Barium Sulphate precipitate.
