The solubility product values of barium sulphate and barium carbonate are 1.0 × 10 –10 and 5.0 × 10 –9 respectively When the two salts are simultaneously equilibrated in pure water the ratio of SO 4 2 − CO 3 2 − is

Options

  1. A0.02
  2. B0.10
  3. C0.05
  4. D0.12

Correct answer

A. 0.02

Step-by-step solution

K sp 1 = Ba 2 + SO 4 2 - K sp 2 = Ba 2 + CO 3 2 - K sp 1 K sp 2 = SO 4 2 - CO 3 2 - = 1 × 1 0 - 1 0 5 × 1 0 - 9 = 0.02
