Verified Answer
Rahul added 2 mL of barium chloride solution to 2 mL sodium sulphate ...
These two solutions react to form a white insoluble precipitate.
BaCl2 ​+ Na2SO4 ​ → 2NaCl + BaSO4 ​ ↓
This is a double displacement reaction as the two compounds exchange their ions to form two different compounds.

Rahul added 2 mL of barium chloride solution to 2 mL sodium sulphate ...
Explanation:


When barium chloride is added to sodium sulphate, a double displacement reaction takes place. Barium sulphate is an insoluble compound and precipitates out of the solution. Thus, option D, "a white solid settled at the bottom" is the correct answer.

Double displacement reaction:

  • Barium chloride (BaCl2) + Sodium sulphate (Na2SO4) → Barium sulphate (BaSO4) + Sodium chloride (NaCl)



Observations:

  • A clear solution was not obtained, so option A is incorrect.

  • Two solutions did not form separate layers in the test tube, so option B is incorrect.

  • The solution did not turn pink, so option C is incorrect.

  • A white solid settled at the bottom, indicating the formation of a precipitate, so option D is correct.
