Assertion : Addition of silver ions to a mixture of aqueous sodium chloride and sodium bromide solution will first precipitate AgBr\mathrm{AgBr} rather than AgCl\mathrm{AgCl}. Reason : KspK_{s p} of AgCl<Ksp\mathrm{AgCl} < K_{s p} of AgBr\mathrm{AgBr}

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both 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

C. If assertion is true but reason is false

Step-by-step solution

KspK_{s p} of AgCl>Ksp\mathrm{AgCl}>K_{s p} of AgBr\mathrm{AgBr}. For the precipitation to occur, its ionic product should exceed solubility product.
