Chapter 17.3, Problem 30SSC

Interpretation Introduction

Interpretation:

The difference between $\text{ KSP}$ and $\text{QSP}$ is to be explained and $\text{QSP}$ is equilibrium constant or not is also be explained.

Concept introduction:

Ionic product is defined as the product concentration of the ions of the electrolyte raised to the power of their stoichiometric coefficients in a balanced chemical equation.

Answer to Problem 30SSC

Solubility product is applicable only for saturated solutions but ionic product are applicable for all types of solutions. Solubility product has constant value for an electrolyte but value of ionic product is not constant.

Explanation of Solution

The solubility product involves the multiplication of concentration of its integrants ions with ion concentrations raised to the power which is equal to number of ions of product and reactants present in electrochemical cell reaction. On the other hand, when multiplication of ion’s concentration of an electrolyte each term raised to the power of their number of ions in a balanced chemical equation at any concentration of the solution, ionic product is calculated. So, the value of ionic product is not constants while the solubility product has a fixed value.

Conclusion

Ionic product can be calculated for all type of solutions on the other hand solubility product is calculated only for saturated solutions.
