Solubility of calcium phosphate (molecular mass, M) in water is W g per 100 mL at 25°C. Its solubility product at 25°C will be approximately.

Options

  1. A1 0 9 W M 5
  2. B1 0 7 W M 5
  3. C1 0 5 W M 5
  4. D1 0 3 W M 5

Correct answer

B. 1 0 7 W M 5

Step-by-step solution

Solubility S = 10 W M m o l e / l i t K s p of C a 3 ( P O 4 ) 2 = 108 S 5 = 108 × 1 0 5 W M 5
