capable of being dissolved
homogeneous mixture of two or more substances in a single phase
the dissolving medium
the substance dissolved in a solution
a substance that dissolves in water to give a solution that conducts electric current
a substance that dissolves in water to give a solution that does not conduct an electric current
mixtures or solutions in which the atoms of two or more elements, usually metals, are uniformly mixed
heterogeneous mixture of a solvent like substance with particles that slowly settle out
particles that are intermediate in size between those in solutions and suspensions form mixtures know as collodial dispersions or,
solution equilibrium
physical state in which the opposing processes of dissolving and crystallizing of a solute occur at equal rates
saturated solution
a solution that contains the maximum amount of dissolved solute... (CG sucks)
unsaturated solution
a solution that contains less solute than a saturated solution
supersaturated solution
a solution that contains more dissolved solute than a saturated solution
the amount of that substance required to form a saturated solution with a specific amount of solvent at a specified temperature
substances that are not soluble in each other
two substances that are mutually soluable in all proportions
Henry's Law
the solubility of a gas in a liquid is directly proportional to the partial pressur eof that gas on the surface of the liquid
the rapid escape of a gas from a liquid in which it is dissolved
heat of solution
the amount of heat energy absorbed or released when a solute dissolves in a specific amount of solvent
a solute molecule or ion surrounded by solvent molecules
a measurement of the amount of solute in a given amount of solvent or solution
the number of moles of solute in one liter of solution
percent by mass
the number of grams of solute dissovled in 100 g of solution
the concentration of solution expressed in moles of solute per kilograms of solvent
a substance that has little tendency to become a gas under existing conditions
colligative property
a property that depends on the number of solute particles but is independant of their nature
molal freezing point constant (Kt)
the freezing point depression of the solvent in a 1 molal solution of a nonvolitle, molecular solute
freezing point depression
the difference between the freezing poitns of the pure solvent and a nonelectrolyte soltuion in that solvent and is directly proportional to the molal conentration of hte solution
molal boiling point constant(Kb)
the boiling point elevation of the solvent in a 1 molal solutionof a nonvolatile molecular solution
boiling point elevation
the difference between the boiling points of the pure solvent and a nonelectrolyte solution in tha tsolvent and is directly proportional to the molal concentraion of the solution
aqueous solution
a solution in which water is the solvent
process with water as the solvent
heat of hydration
the energy released when ions become surrounded by water molecule
the separation of ions that occurs when an ionic compound dissolves
spectator ions
ions that do not take part in a chemical reaction and are found in solution both before and after the reaction
net ionic equation
includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution and does not include spectator ions
the formation of ions from solute molecules by the action of the solvent
H30+ ion
strong electrolyte
any substance that is present in dilute aqueous solution as entirely hydrated
weak electrolyte
a solute that yields a relatively low concentration of ions in aqueous solution
traditional acid
a chemical compound that contains hydrogen and ionized in aqueous solutions to form hydrogen ions
Bronsted acid
a molecule or ion that is a proton doner
Lewis Acid
an atom, ion, or molecule that is an electron-pair acceptor
strong acid
an acid that is a strong electrolyte and ionizes 100% in aqueous solutions
monoprotic acid
an acid that can donate one proton (hydrogen ion) per molecule
