Question
The volume of the water needed to dissolve 1 g of BaSO4 (KSP = 1.1 × 10-10) at 25oC is:
Options
A.280 litre
B.410 litre
C.205 litre
D.None of these
Solution
Solubility of BaSO4 = 
= 1.05 × 10-5 M
∴ wt. of BaSO4 = 1.05 × 10-5 × 233 = 244.37 × 10-5 g/litre.
∴ Volume of water needed to dissolve 1g BaSO4 is equal to
= 410 litre
= 1.05 × 10-5 M∴ wt. of BaSO4 = 1.05 × 10-5 × 233 = 244.37 × 10-5 g/litre.
∴ Volume of water needed to dissolve 1g BaSO4 is equal to
= 410 litreCreate a free account to view solution
