Concept introduction:
The amount of solute dissolved in a given volume of the solvent to form a saturated solution at a given temperature is termed as solubility of the solute in the solvent, at that temperature.
The solubility product of the sparingly soluble salt is given as the product of the concentration of the ions raised to the power equal to the number of times the ion occurs in the equation, after dissociation of the electrolyte.
Number of moles of solute dissolved per litre of solution is called molar solubility.
The number of moles of compound are calculated by the expression:
The mole is converted into the concentration by dividing with volume.
At a given temperature, the product of molar concentrations of the ions of a salt present in the solution is known as the solubility product of the salt. It is represented by
Higher is the value of solubility product of a salt, higher is its solubility.
The presence of common ions in the solution decreases the solubility of a given compound.
For a general reaction:
The solubility product can be calculated by the expression as:
Here,
The molar solubility of a compound is directly proportional to the number of molecules present in the given amount of solvent.
