When a student added a few drops of barium chloride solution to sodium sulphate solution, he obtained a white precipitate instantly. Which of the following type of chemical reaction has been carried out by the student?
(1)combination (2)ouble displacement
(3)displacement (4)decomposition
"

Correct answer: (2) double displacement

Explanation: When barium chloride reacts with sodium sulfate, a white precipitate of barium sulphate and sodium chloride salt is formed.

The chemical equation for the reaction is given below:

$BaCl_2 + Na_2SO_4 → 2NaCl + BaSO_4$

This is an example of a double displacement reaction.
