Homework Answers
Solubility of sparingly soluble salt is affected by presence of common ion which may be cation or anion of strong electrolyte. Due to presence of common ion solubility of electrolyte is decreased
So for solubility of PbF2 its solubility is affected by NaF AS IT Have common anion F - AND Pb(NO3)2 As it have common cation Pb2+
