Question 13

Assertion (A): If barium nitrate solution is added to sodium sulphate solution, a white precipitate is formed.

Reason (R): Sodium sulphate solution is white in colour.

  1. Both A and R are true and R is the correct explanation of A.
  2. Both A and R are true but R is not the correct explanation of A.
  3. A is true but R is false.
  4. A is false but R is true.
Answer

A is true but R is false.

Explanation— When barium nitrate solution is added to sodium sulphate salt solution, white precipitate which is insoluble in water is formed. White precipitate is soluble in dil. HCl. Hence, the assertion (A) is true.

Sodium sulphate solution is a colourless solution. Hence, the reason (R) is false.
