Define the terms:
a) Solubility b) Saturated solution c) Unsaturated solution d) Concentration

Explanation

Solubility: The amount of solute present in a saturated solution at a certain temperature is called its solubility.
b) Saturated solution: When no more solute can be dissolved in the solution at a certain temperature, it is said to be a saturated solution.
c) Unsaturated solution: If the amount of solute present in the solution is less than that in the saturated solution is called an unsaturated solution.
d) Concentration of a solution: The concentration of a solution can be defined as the amount (mass) of solute present in a given amount (mass) of solution or the amount (mass) of solute dissolved in a given volume of the solution.
