Chemical And Ionic Equilibrium Result Question 19
19. For a sparingly soluble salt $A _p B _q$, the relationship of its solubility product $\left(L _s\right)$ with its solubility $(S)$ is
(2001, 1M)
(a) $L _s \quad S^{p+q} p^p q^q$
(b) $L _s \quad S^{p+q} p^q q^p$
(c) $L _s \quad S^{p q} p^p q^q$
(d) $L _s \quad S^{p q}(p \cdot q)^{(p q)}$
Show Answer
Answer:
Correct Answer: 19. ( a )
Solution:
- $A_p B_q \rightleftharpoons \underset{p S}{p A}+\underset{q S}{q B}$
$K_{\mathrm{sp}}=(p S)^p(q S)^q=S^{(p+q)} \cdot p^p \cdot q^q$
