Colloid
A mixture consisting of tiny particles that are intermediate in size between those in solutions and those in suspensions and that are suspended in a liquid, solid, or gas.
Emulsion
Any mixture of two or more I miscible liquids in which one liquid is dispersed in the other.
Solution
A homogeneous mixture of two or more substances uniformly dispersed throughout a single phase.
Solute
In a solution, the substance that dissolves in the solvent.
Solvent
In a solution, the substance in which the solute dissolves.
Alloy
A solid or liquid mixture of two or more metals.
Heterogeneous mixture
Composed of dissimilar components.
Decanting
The process of pouring a lighter liquid off of a heavier liquid.
Immiscible
Describes two or more liquids that do not mix with eachother.
Tyndall effect
The scattering of light.
Polar compound
A molecule that has an uneven distribution of electrons.
Suspension
A mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas.
Hydrogen bonding
The intermolecular force occurring when a hydrogen atom that is bonded to a highly electronegative atom of one molecule is attracted to two unshared electrons of another molecule.
Non polar compound
A compound whose electrons are equally distributed among its atoms.
Solubility
The maximum amount of a solute that will dissolve in a given quantity of solvent at a given temperature and pressure.
Concentration
The amount of a particular substance in a given quantity of a mixture, solution, or ore.
Unsaturated solution
A solution that contains less solute than a saturated solution does and that is able to dissolve additional solute.
Saturated solution
A solution that cannot dissolve any more solute under the given conditions.
Supersaturated solution
A solution that holds more dissolved solute than is required to reach equilibrium at a given temperature.
Molarity
An expression of the concentration of a solution in moles of dissolved solute per liter of solution.
Insoluble
Substances that do not dissolve.
Soluble
Substances that dissolve easily in water.
Dilute
A solution that only contains a small amount of solute.
