Aqueous Acid-Base Titrations

Titration is the quantitative addition of a solution of known concentration to

a solution of unknown concentration until the reaction between them is complete to

determine the concentration of the second solution. An acid-base titration is the

quantitative determination of the concentration of an acid or a base. Titration of an acid

with a base requires that the pH, or relative concentrations of the two reactants, be

monitored. pH can be assessed by litmus paper or by indicators, for example,

phenolphthalein, but these methods lack precision. Typically, pH measurement in the

laboratory is done by measuring the cell potential of that sample in reference to a

standard hydrogen electrode. The endpoint or equivalent points can be determined by

the titration curve, which is a plot of the pH of an acidic (or basic) solution that acts as

a function of the amount of base (or acid) added.

Keywords: Acid, Base, Neutralization, pH, Titration curve.
