Answer:The Ksp expression for the system
[tex]K_{sp}=[Pb^{2+}][Cl^-]^2[/tex]
Step-by-step explanation:
The [tex]K_{sp}[/tex] od the substance that solubility product is defined as mathematical product of concentration of dissolved ions raised to the power equal to their stoichiometric coefficient in reaction.
[tex]A_2B_3\rightleftharpoons 2A^{3+}+3B^{2-}[/tex]
[tex]K_{sp}=[A^{3+}]^2\times [B^{2-}]^3[/tex]
For the given system:
[tex]PbCl_2(s)\rightleftharpoons Pb^{2+}+2Cl^-[/tex]
[tex]K_{eq}=\frac{[PB^{2+}][Cl^-]^2}{[PbCl_2]}[/tex]
[tex]K_{eq}\times [PbCl_2]=K_{sp}[/tex]
[tex]K_{sp}=[Pb^{2+}][Cl^-]^2[/tex]
The Ksp expression for the system : [tex]K_{sp}=[Pb^{2+}][Cl^-]^2[/tex]
