SOLUTIONS A homogeneous mixture of two or more substance is called a solution. Usually we think of a solution as a liquid that contains either a solid or a liquid or a gas dissolved in it. However, this is not true. We can also have a solid have a solid solution as in the case of alloys. (a) Components of a Solution: The substances present in a homogeneous solution are called components of the solution. A solution basically has two components, i.e., a solvent and a solute. i) Solvent: The component of a solution which is present in large proportion, is called solvent. Usually, a solvent is the LARGER component of the solution. For example: In the solution of copper sulphate in water, water is the solvent. Similarly, in paints, turpentine oil is the solvent. (ii) Solute: The component of the solution which is present is small proportion is called solute. For example: In the solution of common salt in water, the common salt is solute. Similarly, in carbonated drinks (soda water), carbon dioxide gas in the solute.
