The solubility of BaSO 4 in water is 2 .42 × 10 - 3   gL - 1 at 298   K . The value of its solubility product K sp will be (Given- the molar mass of BaSO 4 = 233   g   mol - 1 )
Options
- A1 .08 × 10 - 14   mol 2   L - 2
- B1 .08 × 10 - 12   mol 2   L - 2
- C1 .08 × 10 - 10   mol 2   L - 2
- D1 .08 × 10 - 8   mol 2   L - 2
Correct answer
C. 1 .08 × 10 - 10   mol 2   L - 2
Step-by-step solution
Solubility of BaSO 4 = 2 .42 × 10 - 3   gL - 1 ∴   s = 2 .42 × 10 - 3 233 = 1 .038 × 10 - 5   mol   L - 1 K sp = s 2 = 1 .038 × 10 - 5 2 = 1 .08 × 10 - 10   mol 2   L - 2
