The volume of dilute hydrochloric acid required to neutralise 25.0 cm3 of sodium hydroxide solution can be found by titration.
In the titration, a few drops of phenolphthalein indicator were added to the sodium hydroxide solution in a conical flask before adding the dilute hydrochloric acid from a burette.
State the colour change of the phenolphthalein indicator at the end point of the titration when the sodium hydroxide solution has just been neutralised.
