The solubility product for a salt of the type AB is 4 × 10 - 8 . What is the molarity of its saturated solution?
Options
- A2 × 10 - 4   mol / L
- B16 × 10 - 16   mol / L
- C2 × 10 - 16   mol / L
- D4 × 10 - 4   mol / L
Correct answer
A. 2 × 10 - 4   mol / L
Step-by-step solution
K sp for AB = s 2 = 4 × 10 - 8 ∴ Molarity of solution = solubility = K sp = 4 × 10 - 8 = 2 × 10 - 4   mol / L
