Liquid Solutions of Solids: Basics and Applications

115-119Solutions are generally encountered in domestic as well as industrial applications and the solution of solid in liquid are the most common type. When a solid solute is added to a solvent, a solution is formed as a result of the interaction between their molecules (ionization or hydrogen bonding), and the solubility depends on the nature of the molecules, temperature and pressure. The relationship of solubility of a solute in a solution and temperature is presented by the solubility curve. The processes of dissolution or crystallization in solution are important and form the basis of many applications. Several processes related to solution and their industrial applications have been highlighted
