Difference Between Ionic Product and Solubility Product

Key Difference – Ionic Product vsSolubilityProduct

Both ionic product and solubility product express the same idea of the product of concentrations of ionic species in a solution. Thekey differencebetween ionic product and solubility product is that离子product is the product of ions in either anunsaturated or saturated solution而溶解性产物是饱和溶液中离子的产物。

The solubility product is a form of the ionic product. The ionic product and solubility product differ from each other based on the type of solution considered.

What is Ionic Product?

离子产物是饱和或不饱和溶液中离子物种浓度的产物。当仅考虑饱和溶液时，离子产物被称为溶解性产物。离子产品一词适用于所有类型的解决方案。

What is Solubility Product?

溶解性产物是化学反应的平衡常数，在该反应中，固体离子化合物溶解以在溶液中产生离子。术语溶解性产品仅用于饱和溶液。溶解性产物用KSP表示。让我们考虑一个例子；

Ag⁺_(aq)+ Cl^–_(aq)→AGCL_(s)

If the solution is saturated from AgCl (silver chloride), there is an equilibrium between soluble ionic species and the AgCl precipitate. The solubility product of this solution can be given as below,

Ksp = [Ag⁺_(aq)][Cl^–_(aq)]

For any given solution (saturated), the solubility product is the product of ionic species raised into their stoichiometric coefficient. For the above example, the stoichiometric coefficients for Ag⁺and Cl^–ions are 1. Hence, the concentrations of those ions are raised into 1.

The smaller the solubility product of a substance, then lower the solubility of that substance. That is because solubility product gives how many dissolved ionic species present in that solution. If the amount of ionic species is a little amount, it indicates that the substance is not well-dissolved in that solvent. Then the solubility product is also low value.

A major factor affecting the solubility product of a substance is temperature. When the temperature of a solution is increased, the amount of solutes dissolved in that can be dissolved in that solution is increased; which means, the solubility of a solute is increased. This leads to the increase of solubility product. Therefore, substances have different solubility products at different temperatures.

概括–Ionic Product vsSolubilityProduct

离子产物和溶解性产物是两个术语，表达了溶液中离子物种的相同概念。离子产物和溶解度产物之间的差异是离子产物是不饱和或饱和溶液中离子的产物，而溶解性产物是饱和溶液中离子的产物。
