As this is being done he pH of the solution is monitored. A titration curve is generated by plotting the solution's pH versus the volume of the added titrant (Figure 1). At the equivalence point, the number of "equivalents" (or moles if the acid is monoprotic) of acid is exactly equal to the number of equivalents of base. Thus, at the equivalence point the titrated solution is "neutralized" 14 Titration Curve 1 Z Hd 66 14 Titration Curve 2 Hd (stoichiometrically speaking - the pH need not be 7). The equivalence point is identified as the point where the titration curve has the greatest slope (which may be either positive or negative). | Volume of added titrant Figure 1.
