Solution

Phenolphthalein is an indicator that can be used to identify the nature of a substance as acidic, basic or neutral. (1 mark)

It remains colourless when added to an acidic or a neutral substance. But it turns pink when added to a basic substance. (1 mark)

Since distilled water is neutral in nature, phenolphthalein reminas colourless when added to it. (1 mark)
