acid
a solution that contains more hydrogen ions than hydroxide ions
base
a solution that contains more hydroxide ions than hydrogen ions
Arrhenius model
states that an acid is a substance that contains hydrogen and ionizes to produce hydrogen ions in aqueous solution
Bronsted-Lowry model
a model of acids and bases in which an acid is a hydrogen-ion donor and a base is a hydrogen-ion acceptor
Lewis model
a lewis acid is an electron-pair acceptor and a lewis base is an electron-pair donor
Strong acid
an acid that ionizes completely in aqueous solution
Weak acid
an acid that is only slightly ionized in aqueous solution
Strong base
A base that dissociates completely into ions in solution.
Weak base
A base that does not dissociate completely into ions in solution.
pH
measure of how acidic or basic a solution is; the scale ranges from below 0 to above 14; solution with pH above 7 is basic and a pH below 7 is acidic
buffer
an ionic compound that resists changes in its pH
