The K s p for X 2 S O 4 at 25 ° C ( X + is a monovalent ion) is 3.2 × 1 0 - 5 . The maximum concentration of X + that could be attained in a saturated solution of this solid at 25 ° C is

Options

  1. A4 × 1 0 - 2 M
  2. B2.89 × 1 0 - 4 M
  3. C3 × 1 0 - 3 M
  4. D6 × 1 0 - 2 M

Correct answer

A. 4 × 1 0 - 2 M

Step-by-step solution

X 2 S O 4 ⇌ 2 X + + S O 4 2 - K s p = ( 2 S ) 2 × S = 4 S 3 4 S 3 = 3.2 × 1 0 - 5 or S 3 = 8 × 1 0 - 6 S = 2 × 1 0 - 2 . x + = 2 S =2 × 2 × 10 − 2 = 4 × 10 − 2
