A chemical dye whose color is affected by acidic and basic solutions.
acid ionization constant
The value of the equilibrium constant expression for the ionization of a weak acid.
Describes water and other substances that can act as both acids and bases.
A model of acids and bases; states that an acid 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 solution.
base ionization constant
The value of the equilibrium constant expression for the ionization of a base.
A model of acids and bases in which an acid is a hydrogen-ion donor and a base is a hydrogen acceptor.
The species produced when a base accepts a hydrogen ion from an acid.
conjugate acid-base pair
Consists of two substances related to each other by the donating and accepting of a single hydrogen ion.
The species produced when an acid donates a hydrogen ion to a base.
ion product constant for water
The value of the equilibrium constant expression for the self-ionization of water.
A reaction in which an acid and a base react in aqueous solution to produce a salt and a water.
The negative logarithm of the hydrogen ion concentration of a solution; acidic solutions have pH values between 0 and 7, basic solutions have values between 7 and 14, and a solution with a pH of 7.0 is neutral.
The negative logarithm of the hydroxide ion concentration of a solution; a solution with a pOH above 7.0 is acidic, a solution with a pOH below 7.0 is basic, and a solution with a pOH of 7.0 is neutral.
An ionic compound made up of a cation from a base and an anion from an acid.
An acid that ionizes completely in aqueous solution
A base that dissociates entirely into metal ions and hydroxide ions in aqueous solution.
The process in which an acid-base neutralization reaction is used to determine the concentration of a solution of unknown concentration.
An acid that ionizes only partially in dilute aqueous solution.
A base that ionizes only partially in dilute aqueous solution to form the conjugate acid of the base and hydroxide ion.
Contains more hydrogen ions than hydroxide ions.
Contains more hydroxide ions than hydrogen ions.
