The main differences between solubility product and ionic product are given as under:
| Solubility product | Ionic product |
| Solubility product is the concentration of ions of electrolyte, each raised to the power of their coefficients in the balanced chemical equation in a saturated solution. | It is the product of concentration of ions of the electrolyte, each raised to the power of their coefficients in the balanced chemical equation in solution at any concentration. |
| Applicable only to saturated solutions. | Applicable to all types of solutions of any concentration. |
| At constant temperature, its value is constant for a given electrolyte. | The value keeps changing with concentration. |
