Chap 16 - Solutions

Key terms to know to be successful in this chapter.

AB
MiscibleCapable of being mixed,
Boiling-Point ElevationDescribes 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.,
Colligative PropertyProperties of solutions that depend on the number of particles in a volume of solvent and not on the mass of the particles.,
Concentrated SolutionTo concentrate a solution, one must add more solute (e.g. alcohol), or reduce the amount of solvent (e.g. water).,
ConcentrationThe act or process of concentrating, especially the fixing of close, undivided attention.,
Dilute SolutionA solution (liquid mixture) that has a small amount of solute dissolved. As you add more water to a sugar solution the solution, becomes more and more dilute.,
Freezing-Point DepressionThe phenomenon in which the freezing point of a liquid (a solvent) is depressed when another compound is added, meaning that a solution has a lower freezing point than a pure solvent.,
Henry’s LawAt a constant temperature, the amount of a given gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.,
Molal Boiling-Point ElevationThis is the phenomenon of increasing the temperature at which a liquid boils by dissolving another substance in the liquid,
Molal Freezing Point DepressionDescribes the phenomenon in which the freezing point of a liquid (a solvent) is depressed when another compound is added, meaning that a solution has a lower freezing point than a pure solvent.,
MolalityUnit of concentration, defined to be equal to the number of moles of solute divided by the number of kilograms of solvent.,
MolarityIs the number of moles of solute dissolved in one liter of solution.,
Mole FractionIn chemistry, mole fraction x is a way of expressing the composition of a mixture.,
Saturated SolutionA solution in which the maximum amount of solvent has been dissolved. Any more solute added will sit as crystals on the bottom of the container.,
Supersaturated SolutionA solution that contains more solute than it normally would at a given temperature.,
Unsatured SolutionA solution in which more solute can be dissolved at a given temperature is called an unsaturated solution. A given solution that is saturated at a particular temperature may become unsaturated when the temperature is increase.,
ImmiscibleIncapable of mixing,
Henry's Law Equation
Molarity (M) Equation
Percent by Volume Equation
Percent by Mass Equation
Molality Equation
Mole Fractions Equation
Freezing-Point Depression Equation
Boiling-Point Elevation Equation
Moles of Solute Equation
