Class 12 Chemistry - Chapter Solutions NCERT Solutions | Define the term solution. How many types
Define the term solution. How many types of solutions are formed? Write briefly about each type with an example.
A solution is a homogeneous mixtures of two or more than two substances on molecular level.The constitutent of the mixture present in a smaller amount is called the SOLUTE & the one present in larger amount is called the SOLVENT.For eg. Small amount of sugar(solute) dissolved in water(solvent).
SOLUTE + SOLVENT = SOLUTION
There are nine types of solutions formed.They are:

Out of these nine types of solution , solid in liquid, liquid in liquid & gas in liquid are very common.When the components of the solution are mixed,the resulting solution may be in the solid, liquid or gaseous state.They are
(i) Gaseous solution:The solution in which the solvent is a gas is called a gaseous solution. In these solutions, the solute may be liquid, solid, or gas. For example, a mixture of oxygen and nitrogen gas is a gaseous solution.
(ii) Liquid solution:The solution in which the solvent is a liquid is known as a liquid solution. The solute in these solutions may be gas, liquid, or solid.
(iii) Solid solutions: The solution in which the solvent is a solid is known as a solid solution.The solute in these solutions may be a gas, liquid or solid. For example, a solution of copper in gold is a solid solution.
