Types of Solution

In a solution, componets may be solid, liquid or gas. On this basis solutions can be divied into following three types -

  • Gaseous solution
  • Liquid solution
  • Solid solution

Gasesous Solution

Solutions in which solvent is present is gasesous state are called Gasesous solution. Gaseous solutions can be divided into following three types on the basis of phases of solute and solvent.

  • Gas - Gas Solution
  • Liquid - Gas Solution
  • Solid - Gas Solution

Gas - Gas Solution

Solutions in which solute and solvent both are gases; are called Gas-gas Solutions. For example - solution (mixture) of nitrogen and oxygen, solution (mixture) of carbon dioxide and nitrogen, solution (mixture) of carbon dioxide and oxygen, etc.

Liquid Gas Solution

Solutions, in which solute is in liquid state and solvent is in gaseous state, are called Liquid-Gas Solution. For example - solution (mixture) of chloroform in nitrogen gas.

Solid Gas Solution

Solutions, in which solute is in solid state and solvent is in gasesous state, are called Solid-Gas Solutions. For example - Solution (mixture) of camphor in nitrogen gas.

Liquid Solution:

Solutions, in which solvent is present in liquid state, are called Liquid solutions. Liquid solutions can be classified into following three types -

  • Gas - Liquid Solution
  • Liquid - Liquid Solution
  • Solid - Liquid Solution

Gas - Liquid Solution

Solutions having solute in gaseous state and solvent in liquid state, are called Gas - Liquid Solutions. For example - Solution (mixture) of oxygen in water, mixture of carbon dioxide in water. Coca cola, a beverage, is an example of gas - liquid solution, as it has carbon dioxide dissolved in water.

Liquid - Liquid Solution

Solutions, in which solute and solvent both are present in liquid state, are called liquid liquid solutions. For example - Vinegar solution, vinegar is the mixture of ethanoic acid and water. Solution of ethanol in water, etc.

Solid - Liquid Solution

Solutions, in which solutes present in solid state and solvent is in liquid state, are called solid liquid solutions. For example - Solution of salt in water, solution of glucose in water, etc.

Solid Solution

Solutions having solvent in solid state, are called solid solutions. Solid solution can be divided into following three categories:

  • Gas - Solid Solution
  • Liquid - Solid Solution
  • Solid - Solid Solution

Gas - Solid Solution

Solutions having solvent in solid state and solute in gasesous state are called gas-solid solutions. Example - solution of hydrogen in palladium.

Liquid - Solid Solution

Solutions having solvent in solid state and solute in liquid state are called liquid - solid solutions. Example amalgum of mercury with sodium.

Solid - solid solution

Solutions having solvent and solute both in solid state are called solid – solid solutions. Example - Solution of gold and copper.
