Classification of solutions based on the physical state

Classification of solutions based on the physical state:

• Solutions can be classified based on the physical state of the solvent and solute. 
• There are three main types of solutions: solid-solid, liquid-liquid, and gas-liquid.

a. Solid-solid solutions: 

• In a solid-solid solution, both the solvent and solute are in a solid state. 
• This type of solution is also known as a solid solution. 
• An example of a solid-solid solution is an alloy, such as brass, which is a mixture of copper and zinc.

b. Liquid-liquid solutions: 

• In a liquid-liquid solution, both the solvent and solute are in a liquid state. 
• This type of solution is also known as a homogeneous mixture. 
• An example of a liquid-liquid solution is a mixture of water and ethanol.

c. Gas-liquid solutions:

•  In a gas-liquid solution, the solvent is in a liquid state and the solute is in a gaseous state. 
• This type of solution is also known as a heterogeneous mixture.
• An example of a gas-liquid solution is carbonated water, where carbon dioxide gas is dissolved in water.
