Question

_{What will you observe when barium chloride is added to sodium sulphate solution.}

Answer 1

• When barium chloride (BaCl₂) is added to sodium sulphate (Na₂SO₄) solution, a white precipitate of barium sulphate (BaSO₄) along with sodium chloride (NaCl) is formed.

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