• A homogeneous mixture of two or more non-reactive substances is called solution. Solution is prepared by dissolving one or more substances in another substance.
  • Solute and solvent are the two components of the solution. The dissolved component is called solute whereas component in which solute is dissolved is referred to as solvent. A solution will contain only one solvent but can contain many solutes.
  • Physical properties such as density and refractive index are uniform throughout the solution. However, these properties can vary depending on solvent and solute ratio. For example, physical properties of a 10 % (w/w) sugar solution will be different from 20% (w/w) sugar solution.
