Unit 6b Chemistry
Terms in this set (29)
Solution where at least on of the materials is a metal
of or containing water
the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid.
Boiling Point Elevation
describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent.
properties of solutions that depend on the ratio of the number of solute particles to the number of solvent molecules in a solution
Heterogeneous mixture that does not clearly separate.
solution that has a relatively large amount of solute dissolved into a relatively small amount of solvent
Ratio of the amount of solute per amount of solvent (solute/solvent)
Solution that has a relatively low amount of solute dissolved into a relatively high amount of solvent
Freezing Point Depression
The decrease of the freezing point of a solvent because another compound or element is added.
Mixture of 2 or more pure substances in different physical states;
Mixture of 2 or more pure substances in the same physical state; constant composition
that will not dissolve in a solvent even after mixing
forming a homogeneous mixture when added together.
combination of two or more pure substances
A unit of measurement for a chemical substance.
Parts Per Million
The mass of a chemical or contaminate per unit volume of water.
Percent by Mass
calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100
Percent by Volume
measure of concentration of a substance in solution expressed as the ratio of the volume of the solution to the total volume of the solution multiplied by 100
solid product that falls to the bottom of a mixture/solution following a double replacement reaction
When a substance has just enough of another substance in it
a measure of how much solute will dissolve in a certain amount of solvent at a given temperature
able to dissolve
homogeneous mixture composed of two or more substances.
Substance that dissolves
Substance doing the dissolving
There is too much of a substance trying to dissolve in another one creating a precipitate
heterogeneous mixture in which solute-like particles settle out of a solvent-like phase sometime after their introduction
Substance has room for more to dissolve in it.
