Question

Identify the type of the following reaction. Also write a balanced chemical equation for the reaction.

A reaction in which an insoluble substance is formed.

Answer 1

Precipitation reaction: A white precipitate of barium sulphate forms along with sodium chloride solution when sodium sulphate solution is introduced to barium chloride solution. It is referred to as a precipitation reaction because white BaSO₄ precipitate is produced.

\[\ce{\underset{(Sodium sulphate)}{Na2SO4(aq)}+\underset{(Barium chloride)}{BaCl2(aq)}->\underset{(Barium sulphate)}{BaSO4(s)}+ \underset{(Sodium chloride)}{2NaCl(aq)}}\]
