We will do this by Titrating the Acetic Acid present with a Strong Base; Sodium Hydroxide (NaOH). The Endpoint of the Titration will be detected using a Phenolphthalein indicator; an acid-base indicator that changes color from clear to pink in going from its acidic form to its basic form.
The pH of the solution at its turning point is pK ln and is the pH at which half of the indicator is in its acid form and the other half in the form of its conjugate base. Indicator Range At a low pH, a weak acid indicator is almost entirely in the HIn form, the color of which predominates. As the pH increases, the intensity of the color of HIn decreases and the equilibrium is pushed to the right. Therefore, the intensity of the color of In-increases. An indicator is most effective if the color change is distinct and over a small pH range. For most indicators the range is within Â±1 of the pK ln value. The table gives examples of common indicators.
