Comprehensive Classification and Properties of Solutions

Fundamental Concepts of Solutions

• Definition of a Solution: A solution is defined as a homogeneous mixture composed of $2$ or more components.

• Binary Solution: This refers to a specific type of solution that contains exactly $2$ components.

• Solute: The component of a solution that is present in the lesser quantity.

• Solvent: The component of a solution that is present in the larger amount.

• Aqueous Solution: A solution where the solvent is water.

Classification of Solutions by Physical State

• Solutions are classified into $9$ distinct types based on the physical state of the solute and the solvent. These categories are grouped into gaseous, liquid, and solid solutions.

Gaseous Solutions

• Gas in Gas:

  • Solute: Gas
  • Solvent: Gas
  • Example: Air

• Liquid in Gas:

  • Solute: Liquid
  • Solvent: Gas
  • Example: Chloroform mixed with $Ne$

• Solid in Gas:

  • Solute: Solid
  • Solvent: Gas
  • Example: Camphour in $Ne$

Liquid Solutions

• Gas in Liquid:

  • Solute: Gas
  • Solvent: Liquid
  • Example: Soda water

• Liquid in Liquid:

  • Solute: Liquid
  • Solvent: Liquid
  • Example: Vinegar, ethenolene water

• Solid in Liquid:

  • Solute: Solid
  • Solvent: Liquid
  • Example: Sugar in water

Solid Solutions

• Gas in Solid:

  • Solute: Gas
  • Solvent: Solid
  • Example: Hydrogen in Nickel

• Liquid in Solid:

  • Solute: Liquid
  • Solvent: Solid
  • Example: Sodium amalgam

• Solid in Solid:

  • Solute: Solid
  • Solvent: Solid
  • Example: Bronze, copper in gold
