NEET Questions Solved


For a sparingly soluble salt ApBq, the relationship of its solubility product (Ls) with its solubility (s) is:

(a) Ls =sp+q.pp.q                          (b)  Ls =sp+q.pq.qp  

(c) Ls =spq.pp.q                             (d)  Ls = spq.(pq)p+q

(a) ApBq pA+ + qB- ; Let solubility be s mol/litre, Thus

                  p.s       q.s

                    Ksp = [A+]p[B-]q = (ps)p.(qs)q 

                          = ppqq(s)p+q
