15 Titration Curves for Complex Acid/Base Systems (1) Two acids or two bases of different strength. (2) An acid or a base that has two or more acids or bases of different strengths. Acid-Base Titration Curves • Titration curves – plots of pH versus the volume of titrant added during titration • Equivalence point (E) – a point along the course of the titration at which the . Titrations between a weak acid and a weak base have titration curves which are highly irregular. Because of this, no definite indicator may be appropriate and a pH meter is often used to . reaction between an acid and a base, a titration is useful for measuring the pH at various points throughout the reaction. A titration curve is a graph of the pH as a function of the amount of titrant (acid or base) added. 1- Strong Acid-Strong Base Titrations Here is an example of a titration curve, produced when a strong base is. titration curve is a graph of the pH as a function of the amount of titrant (acid or base) added. Here is an example of a titration curve, produced when a strong base is added to a strong acid. This curve shows how pH varies as M NaOH is added to mL of M HCl. Acid-Base Titration Curves • Titration curves – plots of pH versus the volume of titrant added during titration • Equivalence point (E) – a point along the course of the titration at which the acid and the base are present in equivalent (stoichiometric) amounts and consume each other completely.
