What is the common ion effect?
The decrease in solubility of a sparingly soluble salt when a soluble salt containing a common ion is added to the solution.
What is a common ion?
An ion that is present in two or more different compounds in a solution.
Define solubility product, .
The equilibrium constant for the dissolution of a sparingly soluble salt.
What is molar solubility?
The number of moles of solute that dissolve in one liter of a saturated solution.
State Le Chatelier's Principle.
If a change of condition is applied to a system in equilibrium, the system will shift in a direction that relieves the stress.
What is the effect of adding a common ion to a solution of a sparingly soluble salt?
It decreases the solubility of the sparingly soluble salt.
What happens to the equilibrium when a common ion is added?
The equilibrium shifts towards the formation of the solid salt, reducing its solubility.
What is the effect of increasing the concentration of in a solution containing ?
The solubility of decreases.
What is the effect of dissolving in a solution containing ?
The solubility of decreases due to the presence of the common ion, .
What is the effect of adding to a solution of ?
The solubility of decreases.
