Which precipitate is formed when aqueous barium chloride reacts with aqueous sodium sulphate?
Answer and explanation
Correct answer: Barium sulphate
This is a double-displacement reaction: \(\mathrm{BaCl_2(aq) + Na_2SO_4(aq) \rightarrow BaSO_4(s) + 2NaCl(aq)}\). The \(\mathrm{Ba^{2+}}\) and \(\mathrm{SO_4^{2-}}\) ions form insoluble white \(\mathrm{BaSO_4}\), so barium sulphate is the precipitate. Sodium chloride remains dissolved in water.
