TITRATION THEORY
Spectrophotometric Titration
A titration in which the end point is marked by a change in the color and/or color
intensity.
Stoichiometry
The quantitative relationship of the reactants and products in a chemical reaction.
Titrant
The chemical added in a titration that causes the given reaction to occur.
Titration
A quantitative, volumetric procedure used in analytical chemistry to determine the
concentration of an analyte in solution. The concentration of the analyte is determined
by slowly adding a titrant to the solution. As the titrant is added, a chemical reaction
between the titrant and the analyte occurs.
Titration Curve
A graph containing the physical data obtained for a titration. The data plotted is often
an independent variable (volume of titrant) vs. a dependent variable (pH of the solution).
From the titration curve, the equivalence point or end point can be determined.
