Solutions

Solutions are homogeneous mixtures where one substance (solute) is uniformly dissolved in another substance (solvent), forming a stable and consistent blend at the molecular level.

Solutions

A solution represents one of the most fundamental concepts in both scientific and abstract contexts, serving as a bridge between pure substances and complex mixtures. While most commonly associated with liquid combinations, solutions exist across all states of matter.

Physical Chemistry of Solutions

Components

  • Solvent: The dominant substance that does the dissolving (e.g., water in tea)
  • Solute: The substance being dissolved (e.g., sugar crystals)
  • Solubility: The maximum amount of solute that can dissolve in a given amount of solvent

Types by State

  1. Liquid solutions (most common)
    • Liquid in liquid (e.g., alcohol in water)
    • Solid in liquid (e.g., salt water)
    • Gas in liquid (e.g., carbonated beverages)
  2. Solid solutions (e.g., metal alloys)
  3. Gaseous solutions (e.g., air)
