The correct option is C Ag A 2 CO 3 and Agl The salts AgCl , Agl , PbCrO 4 are of same type AB. So, Solubility =√ K sp so, Solubility AgCl =1 × 10-5 M Solubility Agl =1 × 10-8 M Solubility PbCrO 4=2 × 10-7 M For Ag 2 CO 3, Solubility Ag 2 CO 3=(( K S P /4))(1/3)=10-4 Thus, most soluble is Ag 2 CO 3 and least soluble is Agl
