Adding 80g of sugar to 25 g of H 2 O. Concept introduction: Solubility: It is defined as the amount of a given substance that can be dissolved in the certain amount of solvent. Depending upon the solubility and nature of solutions they can be divided into two types. A saturated solution contains the maximum quantity of a solute that dissolves at that temperature. An unsaturated solution contain less than the maximum amount of solute that can dissolves at a particular temperature.
