Solution: A solution is a homogeneous mixture of two or more pure substances. It means their composition and properties are uniform throughout the solution. Solute and solvent are two components of a solution.
Types of solutions: On the basis of different states of solute and solvent solutions are of three types mainly, which are further categorized into three.
These are listed in the following table with examples.
