The solubility product (K_(sp)) of the following compound s are given

1.	The solubility product (K_(sp)) of the following compound s are given at 25^(@)C {:("Compound" ,K_(sp)),(AgCl,1.1xx10^(-10)),(Agl,1.0xx10^(-16)),(PbCrO_(4),4.0xx10^(-10)),(Ag_(2)CO_(3),8.0xx10^(-12)),(,):} The mostsoluble and least soluble compound are respectively
Answer» `AGCL and PbCrO_(4)` `AgI and Ag_(2)CO_(3)` `AgCl and Ag_(2)CO_(3)` `Ag_(2)CO_(3)and AgI` Solution :The 1 st three salts are of the type AB for which `S=sqrt(K_(sp))`, i.e., `10^(-5)M(AgCl), 10^(-8) M (AgI), 2xx10^(-7)M (PbCrO_(4))`. Last salt isof the type `A_(2)B` for which `S=(K_(sp)//4)^(1//3)=(2xx10^(-12))^(1//3)~=10^(-4)` M. Thus, most soluble is `Ag_(2)CO_(3)` and least soluble is AgI.
