Define the term solution. How many types of solutions are formed ? Write briefly about each type with an example.

Explanation

A homogeneous mixture of two or more non-reacting substances whose composition varies within certain fixed limits is known as solution.
Types of solutions : 1. When both solute and solvent are in solid state e.g., alloys. 2. When the solute is in solid and solvent is a liquid, e.g., sugar or salt in water. 3. When solute is in solid state and solvent is in gaseous state e.g., iodine vapours in air. 4 When both solute and solvent are in liquid state 2.g., alcohol in water. 5. When solute is in liquid state but solvent is in solid state e.g., zinc amalgam. 6. When solute is in liquid but solvent is in gaseous state e.g., water vapours in air. 7. When both solute and solvent are in gaseous state e.g., air. 8. When solute is in gaseous but solvent is in liquid state e.g., aerated drinks. 9. When solute is in gaseous state and solvent is in solid state e.g., dissolved gases in mineral.
