Titrating citric acid against strong base. ... Phenolphthalein indicator is an excellent choice for this titration, changing from colourless to pink to red. In comparison to titrations with a strong acid such as hydrochloric acid, the diluted weak acid “mops up” the base in the drops of added titrant more slowly.

Titrating the CITRIC 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.
