Four students were asked to study the reaction between aqueous solutions of barium chloride and sodium sulphate. On mixing the solutions of the two salts in a test tube, they reported their experiment as follows:
(i) The colour of the mixture becomes brown
(ii) The solutions form a separate layer
(iii) a colourless mixture is obtained.
(iv) a white substance settles at the bottom.
The correct report is
- a)(i)
- b)(ii)
- c)(iii)
- d)(iv)
Correct answer is option 'D'. Can you explain this answer?

Explanation:
The reaction between barium chloride and sodium sulphate results in the formation of a white precipitate of barium sulphate and a solution of sodium chloride. The four observations made by the students can be explained as follows:
(i) The colour of the mixture becomes brown:
This observation is incorrect as no brown colour is expected in this reaction. It is possible that the students observed the mixture under inappropriate lighting conditions or made a mistake in their observation.
(ii) The solutions form a separate layer:
This observation is correct. Since the reaction results in the formation of a solid (barium sulphate), it settles at the bottom of the test tube, while the solution of sodium chloride remains on top.
(iii) A colourless mixture is obtained:
This observation is correct. The solution of sodium chloride is colourless, and the white precipitate of barium sulphate does not impart any colour to the mixture.
(iv) A white substance settles at the bottom:
This observation is correct. As mentioned earlier, the white substance is the precipitate of barium sulphate, which settles at the bottom of the test tube.
Therefore, the correct report is option 'D' - (iv) a white substance settles at the bottom.
