any acid that contains one ionizable proton (hydrogen ion); nitric acid (HNO3) is a monoprotic acid
any acid that contains two ionizable protons (hydrogen ions); sulfuric acid (H2SO4) is a diprotic acid
any acid that contains three ionizable protons (hydrogen ions); phosphoric acid (H3PO4) is a triprotic acid
the particle formed when a base gains a hydrogen ion; NH4+ is the conjugate acid of the base NH3
the particle that remains when an acid has donated a hydrogen ion; OH- is the conjugate base of the acid water
conjugate acid-base pair
two substances that are related by the loss or gain of a single hydrogen ion; ammonia (NH3) and the ammonium ion (NH4+) are a conjugate acid-base pair
an aqueous solution in which the concentrations of hydrogen and hydroxide ions are equal; it has a pH of 7.0
ion product constant for water
the product of the concentrations of hydrogen ions and hydroxide ions in water; it is 1 X 10-14 at 25°C
any solution in which the hydrogen-ion concentration is greater than the hydroxide-ion concentration
any solution in which the hydroxide-ion concentration is greater than the hydrogen-ion concentration
a number used to denote the hydrogen-ion concentration, or acidity, of a solution; it is the negative logarithm of the hydrogen-ion concentration of a solution
a base that completely dissociates into metal ions and hydroxide ions in aqueous solution
a base that reacts with water to form the hydroxide ion and the conjugate acid of the base
a reaction in which an acid and a base react in an aqueous solution to produce a salt and water
the point in a titration where the number of moles of hydrogen ions equals the number of moles of hydroxide ions
