|
pOH
|
The negative logarithm of the hydroxide ion concentration of a solution; a solution with a value above 7.0 is acidic; a value below 7.0 is basic; a value of 7.0 is neutral.
|
|
|
acid-base indicator
|
A chemical dye whose color is affected by acidic and basic solutions.
|
|
|
Arrhenius model
|
States that an acid contains hydrogen and ionizes to produce hydrogen ions in solution and a base contains a hydroxide group dissociates to produce a hydroxide ion in solution.
|
|
|
conjugate base
|
The species produced when an acid donates a hydrogen ion to a base.
|
|
|
weak base
|
A base that ionizes only partially in dilute aqueous solution to form the conjugate acid of the base and hydroxide ion.
|
|
|
weak acid
|
An acid that ionizes only partially in dilute aqueous solution.
|
|
|
pH
|
The negative logarithm of the hydrogen ion concentration of a solution; acidic solutions have values between 0 and 7; basic solutions have values between 7 and 14; a value of 7.0 is neutral.
|
|
|
strong base
|
A base that dissociates entirely into metal ions and hydroxide ions in aqueous solution.
|
|
|
basic solution
|
Contains more hydroxide ions that hydrogen ions.
|
|
|
amphoteric
|
Describes water and other substances that can act as both acids and bases.
|
|
|
acidic solution
|
Contains more hydrogen ions than hydroxide ions.
|
|
|
strong acid
|
An acid that ionizes completely 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.
|
|
|
salt
|
An ionic compound made up of a cation from a base an anion from an acid.
|
|
|
conjugate acid
|
The species produced when a base accepts a hydrogen ion from an acid.
|
|
|
neutralization reaction
|
A reaction in which an acid and a base react in aqueous solution to produce a salt and water.
