Saturated solution

Contains the maximum amount of solute for a given quantity of solvent at a constant temperature and pressure

1

Solubility

The amount of solute that dissolves in a given quantity of a solvent at a specified temperature and pressure to produce a saturated solution

2

Unsaturated solution

A solution that contains less solute than a saturated solution at a given temperature and pressure

3

Miscible

Two liquids are this if they dissolve in each other in all proportions

4

Immiscible

Liquids that are insoluble in one another

5

Supersaturated solution

Contains more solute than it can theoretically hold at a given temperature

6

Henry's law

States that at any given temperature, the solubility(S) of a gas in a liquid is directly proportional to the pressure(P) of the gas above the liquid

S1/P1=S2/P2

7

Concentration

A measure of the amount of solute that is dissolved in a given quantity of solvent

8

Dilute solution

Solution that contains a small amount of solute

9

Concentrated solution

Solution that contains a large amount of solute

10

Molarity (M)

The number of moles of solute dissolved in 1 liter of solution

11

Colligative property

A property that depends only upon the number of solute particles, and not upon their identity

12

Freezing-point depression

The difference in temperature between the freezing point of a solution and the freezing point of the pure solvent

13

Boiling-point elevation

The difference in temperature between the boiling point of a solution and the boiling point of the pure solvent

14

Molality (m)

The number of moles of solute dissolved in 1 kilogram (1000g) of solvent

15

Mole fraction (of a solute in a solution)

The ratio of the moles of that solute to the total number of moles of the solvent and solute

XA=nA/nA+nB. XB=nB/nA+nB

16

Molal freezing-point depression constant

The constant which is equal to the change in freezing point for 1-molal solution of a nonvolatile molecular solute

17

Molal boiling-point elevation constant

The constant which is equal to the change in boiling point for a 1-molal solution of a nonvolatile molecular solute
