Dec 11, 2018 · Some substances, such as ethanol and water are soluble in every possible proportion when combined with the right solvent. To be soluble in all proportions is known as miscibility. If the equilibrium solubility of a solution is exceeded, which can happen in certain conditions, the solution is said to be supersaturated and is metastable in nature..

given solute at any temperature can be determined. Solubility curves are obtained expefimentally by determining the salt solubility at different temperatures and plotting the data. Concentration of solutions can be calculated asa. A.
Actually, It is well known to us that the solubilityof the solute in a solution increases with the increase in the temperature because when the temperature increases the molecules of the solvent gain more kinetic energy and decrease the tendency to crystallize. This principle is the basis of the purification technique called recrystallization.
