Definitions[edit]

Polyprotic Acids[edit]

Can donate more than one hydrogen ion. (Bronsted-Lowry)

Titration[edit]

Titration is the combining of a known concentration solution with an unknown concentration solution. The titration is stopped at the equivalence point, where all of the acid or base has been reacted. Polyprotic acids have more than one equivalence point.

Conjugate Acids and Bases[edit]

Conjugates differ by one hydrogen ion. Strong acids have weak base conjugates, and vice versa.

Water Dissociation Constant[edit]

Kw = [H+][OH-] = 10^-14 at 298K.
