A saturated solution of Pb(IO3)2 in pure water has a lead ion concentration of 5.0 x 10-5 Molar. What is the Ksp value of Pb(IO3)2? A. 1.0 x 10-5 Molar B. 5.0 x 10-5 Molar C. 1.0 x 10-13 Molar D. 2.5 x 10-13 Molar E. 5 x 10-13 Molar

Option (E) is correct

Explanation:

Solubility equilibrium of is given as follows-

Hence, if solubility of is S (M) then-

                              and

Where species under third bracket represent equilibrium concentrations

So, solubility product of ,

Here,

So,

So,

Hence option (E) is correct
