The K s p of A g 2 C r O 4 is 1.1 × 1 0 - 12 at 0.1 K . The solubility (in m o l / L ) of A g 2 C r O 4 in a 0.1 M A g N O 3 solution is

Options

  1. A1.1 × 1 0 - 11
  2. B1.1 × 1 0 - 10
  3. C1.1 × 1 0 - 12
  4. D1.1 × 1 0 - 9

Correct answer

B. 1.1 × 1 0 - 10

Step-by-step solution

Ag 2 CrO 4 s ⇌ 2 Ag + aq 2 s + 0.1 + CrO 4 2 − aq s K s p = ( 0.1 ) 2 s = 1.1 × 1 0 - 12 s = 1.1 × 1 0 - 10 M
