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
- 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)
- Solid solutions (e.g., metal alloys)
- Gaseous solutions (e.g., air)
Properties and Characteristics
Solutions exhibit several distinctive properties:
- Homogeneity throughout
- Colligative Properties dependent on solute concentration
- Transparency (unless colored by constituent components)
- Phase Equilibrium under normal conditions
