unit 9: Solutions

soluble Capable of dissolving in a particular solvent
solution A homogeneous mixture of two or more substance uniformly dispersed throughout a single phase
solvent in a solution, the substance in which the solute dissolves
solute in a solution , the substance that dissolves in the solvent
suspension a mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas
colloids a mixture consisting of tiny particles that are intermediate in size between those in solutions and those in suspensions and that are suspended in a liquid, solid, or gas
tyndall effect a beam of light distinguishes a colloid from a solution
electrolyte a substance that dissolves in water to give a solution that conducts an electric current
nonelectrolyte a substance that dissolves in water to give a solution that does not conduct an electric current
solution equilibrium the physical state in which the opposing processes of dissolution and crystallization of a solute occur at equal rates
saturated solution A solution that cannot dissolve any more solute under the given conditions
unsaturated solution a solution that contains less solute that a saturated solution does and that is able to dissolve additional solute
supersaturated solution a solution that holds more dissolved solute than is required to reach equilibrium at a given temperature
solubility the ability of one substance to dissolve in another at a given temperature and pressure; expressed in terms of the amount of solute that will dissolve in a given amount of solvent to produce a saturated solution
hydration the strong affinity of water molecules for particles of dissolved or suspended substances that causes electrolytic dissociation
immiscible describes two or more liquids that do not mix with each other
miscible describes two or more liquids that can dissolve into each other in various proportions
Henry's law the law that states that at constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas on the surface of the liquid
effervescence a bubbling of a liquid caused by the rapid escape of a gas rather than by boiling
enthalpy of a solution the amount of energy released or absorbed as heat when specific amount of solute dissolves in a solvent
concentration the amount of a particular substance in a given quantity of a mixture , solution, or ore
molarity the concentration of a solution in moles of solute per kilo of solvent
molality the concentration of a solution expressed in moles of solute per kilo of solvent

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
