Learning Objective
Compute the concentration of an unknown acid or base given its volume and the volume and concentration of the standardized titrant.
Key Points
An acid-base titration is a quantitative analysis of acids and bases; through this process, an acid or base of known concentration neutralizes an acid or base of unknown concentration.The titration progress can be monitored by visual indicators, pH electrodes, or both.The reaction's equivalence point is the point at which the titrant has exactly neutralized the acid or base in the unknown analyte; if you know the volume and concentration of the titrant at the equivalence point, you can calculate the concentration of a base or acid in the unknown solution.Termsanalyte the unknown solution whose concentration is being determined in the titrationacid-base titration determines the concentration of an acid or base by exactly neutralizing it with an acid or base of known concentrationequivalence point the point at which an added titrant's moles are stoichiometrically equal to the moles of acid/base in the sample; the smallest amount of titrant needed to fully neutralize or react with the analytetitrant the standardized (known) solution (either an acid or a base) that is added during titration
