A solution that contains more hydrogen ions than hydroxide ions.
acidic solution
A solution that contains more hydroxide ions than hydrogen ions.
basic solution
A model of acids and bases; states that an acis is a substance that contains hydrogen and ionizes to produce hydrogen ions in aqueous solution and a base is a substance that contains a hydroxide group and dissociates to produce a hydroxide ion in aqueous
Arrhenius Model
A model of acids and bases in which an acid is a hydrogen-ion donor and a base is a hydrogen-ion acceptor.
Bronsted-Lowry Model
The species produced when a base accepts a hydrogen ion from an acid.
Conjugate acid
The species produced when an acid donates a hydrogen ion to a base.
Conjugate base
Consists of two substances related to each other by the donating and accepting of a single hydrogen ion.
Conjugate acid - base pair
Describes water and other substances that can act as both acids and bases.
amphoteric
An acid that ionizes completely in aqueous solution.
strong acid
An acid that ionizes only partially in dilute aqueous solution.
weak acid
A base that dissociates entirely into metal ions and hydroxide ions in aqueous solution.
strong base
A base that ionizes only partially in dilute aqueous solution to form the conjugate acid of the base and hydroxide ion.
weak base
