Study Notes
Solution Science Overview
- A solution is a liquid mixture with a uniform distribution of the solute (minor component) within the solvent (major component).
- Mixture refers to a substance formed by combining various substances together.
- Solute is the substance dissolved in the solvent, usually present in a lesser quantity in a solution.
- A solvent is the medium in which the solute is dissolved, forming a solution.
Rates and Factors of Dissolution
- Rate of solution refers to the process of dissolution when a solute dissolves in a solvent, influenced by various factors.
- Increasing the surface area of the solute or breaking it into smaller pieces enhances the rate of solution.
- Stirring the mixture helps bring fresh solvent into contact with the solute, speeding up dissolution.
Key Concepts of Solubility
- Solubility is a property quantifying how much solute can dissolve in a solvent, measured at equilibrium as a saturated solution.
- Concentration relates to the abundance of a component within a mixture, described through various mathematical terms like mass or molar concentration.
Types of Solutions
- A concentrated solution has a high amount of solute compared to the solvent.
- A dilute solution results from mixing more solvent with a solution, lowering the solute concentration.
- A saturated solution is at maximum solute capacity; additional solute results in precipitation or gas release.
- An unsaturated solution can still accommodate more solute without reaching saturation.
- A supersaturated solution contains more solute than typically possible under standard conditions.
Miscellaneous Properties
- Insoluble substances cannot dissolve in a solvent.
- Heterogeneous mixtures consist of components with non-uniform distribution, visible localized regions differing in properties.
- Alloys are metallic materials composed of multiple elements, with at least one being a metal, exhibiting unique properties distinct from their components.
- A colloid contains particles ranging from 1 to 1000 nanometers that remain dispersed within the solution without settling out.
