acid
a compound that produces hydrogen ions in a solution
acid dissociation constant
the ratio of the concentration of the dissociated form of an acid to the undissociated form
acidic solution
any solution in which the hydrogen ion concentration is greater than the hydroxide ion concentration
alkaline solution
a basic solution
amphoteric
a substance that can act as both an acid and a base
base
a compound that produces hydroxide ions in a solution
base dissociation constant
the ratios of the concentration of the dissociated form of a base to the dissociated form
basic solution
any solution in which the hydroxide ions concentration is greater than the hydrogen ion concentration
conjugate acid
the particle formed when the base gains a hydrogen ion
conjugate acid-base pair
2 substances that are related by the loss or gain of a single hydrogen ion
conjugate base
the particle that remains when an acid has donated a hydrogen ion
diprotic acid

hydrogen ion acceptor
a base
hydrogen ion donor
an acid
hydronium ion

ion-product constant for water
the product of the hydrogen ion and hydrogen ion concentrations in water
Lewis acid
any substance that can accept a pair of electrons to form a covalent bond
Lewis base
any substance that can donate a pair of electrons to form a covalent bond
monoprotic acid
any acid that contains one ionizable proton
neutral solution
an aqueous solution in which the concentrations of hydrogen and hyroxide ions are equal
pH
a number used to denote the acidity of a solution
self-ionization
describes the reaction in which two water molecules react to produce ions
strong acid
an acid that is almost completely ionized in an aqueous solution
strong base

weak acid
an acid that is only slightly ionized in aqueous solution
weak base
a base that does not dissociate completely in aqueous solution
