Ch 13: Solutions Flashcards
soluble
capable of being dissolved
solution
a homogeneous mixture of two or more substances in a single phase
solvent
the dissolving medium in a solution
solute
the substance dissolved in a solution
suspension
if the particles in a solvent are so large that they settle out unless the mixture is constantly stirred or agitated, the mixture is called a suspension
colloids
particles that are intermediate in size between those in solutions and suspensions form mixtures known as colloidal dispersion’s, or colloids
electrolyte
a substance that dissolves in water to give a solution that conducts electric current
nonelectrolyte
a substance that dissolves in water to give a solution that does not conduct an electric current
solution equilubrium
the physical state in which the opposing processes of dissolution and crystallization of a solute occur at equal rates
saturated solution
a solution that contains the maximum amount of dissolved solute
unsaturated solution
a solution that contains less solute than a saturated solution under the existing conditions
supersaturated solution
a solution that contains more dissolved solute than as saturated solution contains under the same conditions
solubility
the solubility of a substance is the amount of that substance required to form a saturated solution with a specific amount of solvent at a specified temperature
hydration
the solution process with water as the solvent; ions are referred to as hydrated
immiscible
liquid solutes and solvents that are not soluble in each other
miscible
liquids that dissolve freely in one another in any proportion
Henry’s law
the solubility of a gas in a liquid is directly proportional to
the partial pressure of that gas on the surface of liquid
effervescence
the rapid escape of a gas from a liquid in which it
solvated
a solute particle that is surrounded by solvent molecules
heat of solution
the net amount of heat energy absorbed or released when an specific amount of solute dissolves in a solvent
heat of solution
the net amount of heat energy absorbed or released when an specific amount of solute dissolves in a solvent
concentration
the measure of the amount of solute in a given amount of solvent or solution
molarity
the number of moles of solute in one liter of solution
molarity
the concentration of a solution expressed in moles of solute per kilogram of solvent
