# What is the color of phenolphthalein indicator in acidic solution?

Aug 9, 2016

Nada.

#### Explanation:

In acid solution, phenolphthalein is colourless. This is a good indicator to use because at approx. $p H = 10$ a lovely fuchsia (i.e. pinkish) colour is realized. This indicator is very easy to vizualize.
