properties-of-solution
A solution is a mixture of two or more substances in which each substance retains its own chemical identity and properties. In a solution, one substance is called the solvent and the other substance(s) are called solutes. The solvent is always present in greater quantity than the solutes. The solvent can be a liquid, a gas, or a solid. The solutes can be a liquid, a gas, or a solid.
The physical and chemical properties of the solvent and solutes are unchanged in a solution. The properties of a solution depend on the properties of the solvent and solutes. For example, the boiling point of a solution is the boiling point of the solvent. The freezing point of a solution is the freezing point of the solvent. The density of a solution is the density of the solvent.
The electrical conductivity of a solution is the electrical conductivity of the solvent. The solutes do not dissolve in the solvent to any significant extent. The solvent molecules are surrounded by the solute molecules. The solvent molecules are held together by London forces.
