# Chapter 16--Solutions

## 13 terms

### 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.

### saturated solution

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

### unsaturated solution

solution contains less solute than a saturated solution. If additional solute is added it will dissolve until solution becomes saturated.

### miscible

liquids are miscible if they dissolve in each other in all proportions.

### immiscible

liquids that are insoluble in one another

### supersaturated substance

contains more solute then it can theoretically hold at a given temperature.

### Henry's Law

at a given temp, the solubility (S) of a gas in a liquid is directly proportional to the pressure (P) of the gas above the liquid. As pressure above gas decreases, solubility decreases.

### concentration

a measure of the amount of solute dissolved in a given quantity of solvent

### Molarity (M)

the number of moles of solute dissolved in one liter of solution.

### percent solution

when both the solute and the solvent are liquid, we measure the volume of both.

### colligative property

property of solutions that depends only on the number of solute particles, not upon solute identity.

### freezing point depression

the difference in the temp. between the freezing point of a solution and the freezing point of the pure solvent.

### boiling point elevation

the difference in the temp. between the boiling point of a solution and the boiling point of the pure solvent.
