Impact of Common Ion Effect on Solubility
If you observe in the above example, solubility of AgCl was affected due to common ion effect. The other impacts of common ion effect on solubility is as described below,
Decreased Solubility due to Common Ions
As shown in NaCl and AgCl example, the equilibrium shifts due to excess chloride ions and reduces the solubility of AgCl. According to Le Chatelier’s principle, the solution precipitate out AgCl and reduces its solubility in NaCl solution due to the presence of common chloride ions.
Common Ion Effect – Definition, Explanation, Examples
Common ion effect is a phenomenon in chemistry that describes the decrease in solubility of a compound when it is dissolved in a solution that already contains one of its constituent ions. This effect occurs due to the principle of chemical equilibrium and Le Chatelier’s principle.
In this article, we will learn in detail about the common ion effect, its impact on solubility, and its validity in the case of acids, bases, and salts. We will also learn its limitations and FAQs based on the common ion effect.
