Assertion: Sb_2 ~S_3 is not soluble in yellow ammonium sulphide....

Assertion: Sb2 S3\mathrm{Sb}_2 \mathrm{~S}_3 is not soluble in yellow ammonium sulphide. Reason : The common ion effect due to S2−S^{2-} ions reduces the solubility of Sb2 S3\mathrm{Sb}_2 \mathrm{~S}_3.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIfboth assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.
