Solubility product of a salt A B is 1 10⁻⁸ in a solution in which concentration of A is 10⁻³ M . The salt will precipitate when the concentration of B becomes more than
Options
- A10⁻⁴ M
- B10⁻⁷ M
- C10⁻⁶ M
- D10⁻⁵ M
Correct answer
D. 10⁻⁵ M
Step-by-step solution
K_ s p =[A][B] aligned 10⁻⁸ &=10⁻³[B] [B] &=10⁻⁵ M aligned Salt will precipitate when [B]>10⁻⁵
