Calculate the solubility in mol dm ⁻³ of sparingly soluble salt BA if its solubility product 4.9 10⁻¹³ at same temperature.
Options
- A7.0 10⁻⁷
- B7.5 10⁻⁷
- C8.0 10⁻⁷
- D4.9 10⁻⁷
Correct answer
A. 7.0 10⁻⁷
Step-by-step solution
For BA, BA _ ( s ) B _ ( aq ) ⁺+ A _ ( aq ) ⁻ Here, x=1, y=1 array ll & K _ sp =x^x y ^y ~S ^ x+y =(1)^1(1)^1 ~S ¹⁺¹= S ^2 & ~S = K _ sp = 4.9 10⁻¹³ =7.0 10⁻⁷ ~mol dm ⁻³ array
