For a sparingly soluble salt A_ p B_ q , the relationship of its solubility product L s K_ s p with its solubility (S) is
Options
- ALs K _ sp = S ^ pq ( pq )^ P + q
- BLs = S ^ p + q p ^ p q ^ q
- CLs K _ sp = S ^ p + q p ^ q q ^ p
- DLs K _ sp = S ^ pq p ^ P q ^ q
Correct answer
B. Ls = S ^ p + q p ^ p q ^ q
Step-by-step solution
ApBq pA _ Sp ⁺+ qB _ Sq Let the solubility be S mol / liter Thus, aligned K _ sp &= [ A ⁺ ]^ p [ B ⁻ ]^ q &=[ Sp ]^ p [ Sq ]^ q = p ^ p q ^ q ( S )^ p + q aligned
