What is observed when a solution of sodium sulphate is added to a solution of barium chloride in a test tube? Write equation for the chemical reaction involved and name the type of reaction in this case.

Answer:

\[\underset{\begin{smallmatrix}  \text{Sodium} \\  \text{sulphate} \end{smallmatrix}}{\mathop{N{{a}_{2}}S{{O}_{4}}}}\,+\underset{\begin{smallmatrix}  \text{Barium} \\  \text{chloride} \end{smallmatrix}}{\mathop{BaC{{l}_{2}}}}\,\to \underset{\begin{smallmatrix}  \text{Barium} \\  \text{sulphate} \end{smallmatrix}}{\mathop{BaS{{O}_{4}}}}\,+\underset{\begin{smallmatrix}  \text{ Sodium} \\  \text{ chloride} \end{smallmatrix}}{\mathop{2NaCl}}\,\]

It is an example of double displacement reaction.
