The solubility of CuBr is 2 10⁻⁴ ~mol / L at 25^ C . The K_ s p value for CuBr is
Options
- A4 10⁻⁸ ~mol ^2 ~L ⁻²
- B4 10⁻⁴ ~mol ^2 ~L ⁻²
- C4 10⁻¹¹ ~mol ^2 ~L ⁻²
- D4 10⁻¹⁵ ~mol ^2 ~L ⁻²
Correct answer
A. 4 10⁻⁸ ~mol ^2 ~L ⁻²
Step-by-step solution
CuBr Cu ⁺+ Br ⁻ Solubility of CuBr is 2 10⁻⁴ ~mol ~L ⁻¹ Therefore, solubility of Cu ⁺=2 10⁻⁴ ~mol ~L ⁻¹ Solubility product =2 10⁻⁴ 2 10⁻⁴=4 10⁻⁸ ~mol ^2 ~L ⁻²
