Question
For a sparingly soluble salt ApBq, the relationship of its solubility product (LS) with its solubility (S) is
Options
A.LS = Sp + q ⋅pp⋅qq
B.LS = Sp + q⋅pq⋅qp
C.LS = Spq⋅pp⋅qq
D.LS = Spq⋅(pq)p+q
Solution
$A_{p}B_{q}(s) \rightleftharpoons \underset{p.s.M}{pA^{2 +}} + \underset{q.s.M}{qB^{P -}}$
Solubility product $L_{s} = (p.s)^{p}.(q.s)^{q} = p^{p}.q^{q}.s^{(p + q)}$
