Titrating an acid into a base
WebOne of the most common titrations is an acid-base neutralisation, where the concentration of one of the reactants is determined via titration. In the experiment below, methyl orange is used to identify the endpoint of the titration, but some other titrations will use phenolphthalein. The video below outlines the titration procedure.
