When equal volume of the following solutions are mixed, which of the following gives maximum precipitate? ( K s p of A g C l = 1 0 - 12 )

Options

  1. A1 0 - 4 M A g + and 1 0 - 4 M C l -
  2. B1 0 - 3 M A g + and 1 0 - 3 M C l -
  3. C1 0 - 5 M A g + and 1 0 - 5 M C l -
  4. D1 0 - 6 M A g + and 1 0 - 6 M C l -

Correct answer

B. 1 0 - 3 M A g + and 1 0 - 3 M C l -

Step-by-step solution

For precipitation the value of ionic product must be more than K s p so that a super saturated solution is possible and precipitation occurs at once. Here 1 0 – 3 M A g × 1 0 – 3 M C l – > K s p ( 1 0 - 12 ) i.e. precipitation occurs maximum in it.
