A student used a pipette to add 25cm3 of calcium hydroxide of unknown concentration to a conical flask. The student carried out a titration to discover the volume of 0.2 mol/dm3 of hydrochloric acid that would be needed to neutralise the calcium hydroxide. Describe how the student would complete a titration using the following equipment. Include the name of a suitable indicator and the colour change which would be expected to show when neutralisation had occurred.
