The solubility of BaSO4 in water is 2.42×10-3 gL-1 at 298 K. The value of its solubility product Ksp will be
(Given- the molar mass of BaSO4=233 g mol-1)
  1. 1.08×10-14 mol2 L-2
  2. 1.08×10-12 mol2 L-2
  3. 1.08×10-10 mol2 L-2
  4. 1.08×10-8 mol2 L-2

Solution

Solubility of BaSO4=2.42×10-3 gL-1
∴ s=2.42×10-3233=1.038×10-5 mol L-1
Ksp=s2=1.038×10-52
=1.08×10-10 mol2 L-2
