|
Aqueous
|
a homogenous mixture/solution in which a solute is dissolved in water.
|
|
|
Boiling Point
|
the temperature at which a liquid undergoes a phase change from liquid to gas; the temperature at which the vapor pressure of a liquid is equal to the atmospheric pressure.
|
|
|
Boiling Point Elevation
|
the boiling point of a solution is higher than the boiling point of the pure solvent (colligative property)
|
|
|
Concentrated
|
Having a relatively large amount of substance present in a unit amount of mixture. For example, a 12 M HCl solution is more concentrated than an 0.001 M HCl solution.
|
|
|
Concentration
|
A measure of the amount of solute present in a unit amount of mixture. (Ex: ppm = parts per million, molarity = moles solute/liter solution); the process of increasing the amount of substance in a given amount of mixture.
|
|
|
Dilute
|
having a relatively low concentration of solute in a mixture.
|
|
|
Freezing Point Depression
|
the freezing point/melting point of a solution is lower than the freezing point/melting point of the pure solvent (colligative property)
|
|
|
Heterogeneous
|
A sample of matter consisting of more than one pure substance and more than one phase
|
|
|
Homogeneous
|
A sample of matter consisting of more than one pure substance with properties that do not vary within the sample
|
|
|
Insoluble
|
Refers to a substance that does not dissolve in a solvent to any significant degree
|
|
|
13. Miscible
|
Two liquids are considered "miscible" or mixable if shaking them together results in a single liquid phase with no visible separation
|
|
|
Mixture
|
two or more pure substance PHYSICALLY combined; a combination of two or more pure substances that can be separated by physical means
|
|
|
Molarity
|
a measure of concentration; M = moles of solute/liters of solution
|
|
|
Parts Per Million
|
a measure of concentration; ppm = parts of solute/million parts of solution
|
|
|
Percent Composition (by mass or volume)
|
% comp = (part/whole) x 100
|
|
|
Precipitate
|
An insoluble substance that has been formed from a chemical reaction between substances dissolved in a solution
|
|
|
Saturated
|
a solution that has reached equilibrium; a solution which can not dissolve any more solute
|
|
|
Solubility
|
a measure of the concentration of a substance in a saturated solution; a measure of how much of a substance can dissolve in a given amount of solvent
|
|
|
Soluble
|
capable of being dissolved in a solvent
|
|
|
Solution
|
a homogenous mixture
|
|
|
Solute
|
A substance dissolved in a solvent to make a solution
|
|
|
Solvent
|
The most abundant component in a solution
|
|
|
Supersaturated
|
a solution in which the concentration of solute is higher than the solubility; more solute is dissolved than should be under a given set of conditions
|
|
|
Unsaturated
|
A solution with a concentration lower than its equilibrium solubility; a solution in which more solute can be dissolved
|
