Respuesta :

when the salt PbCl is dissolved it dissociates as follows;
PbCl
 ---> Pb²⁺ + 2Cl 
solubility product constant written as ksp is the equilibirum constant for a solid that dissolves in water.
the expression for ksp is; ksp = [Pb
²⁺][Cl]²

Answer:

ksp = [Pb²⁺][Cl⁻]²

Explanation:

Solubility is a product constant which define the equilibrium condition between the elements and their ionic solution. It indicates the extent to which an element can disassociate in water.  

The solubility constant is represented by ksp and is equal to the product of concentration of ions raised to the power of coefficient of ion. Thus ksp for the given equation would be -  

ksp = [Pb²⁺][Cl⁻]²
