fællesioneffekten
The fællesioneffekten, often translated as the common ion effect, is a chemical principle describing the decrease in solubility of a sparingly soluble salt when a soluble salt containing a common ion is added to the solution. This phenomenon is a direct consequence of Le Chatelier's principle.
When a sparingly soluble salt, such as silver chloride (AgCl), is dissolved in water, it establishes an
Consequently, more of the sparingly soluble salt precipitates out of the solution, leading to a decrease in
