Vedclass · Answer

(B) The solubility of a salt is directly related to its solubility product constant $(K_{sp})$.For salts of the same type (e.g.,$AB$ type),the salt with the lowest $K_{sp}$ value is the least soluble.Comparing the given values:$PbCO_3: K_{sp} = 1.0 	imes 10^{-13}$$FeCO_3: K_{sp} = 2.0 	imes 10^{-11}$$CaCO_3: K_{sp} = 4.8 	imes 10^{-9}$$BaCO_3: K_{sp} = 5.0 	imes 10^{-9}$Since $1.0 	imes 10^{-13}$ is the smallest value,$PbCO_3$ is the least soluble carbonate.

Which of the following is the least soluble carbonate?
