it is because it is not a change of the substance (indicator) or of the chemical (NaOH) no new substance is made so it is not a chemical reaction it is a physical change
The indicator does change, it loses a proton. One of the anionic forms of of phenolphthalein is pink. Loss of a proton is a chemical change. A little reading about phenolphthalein will clear this up for ya I'm sure.
@jessiebm123 How do you think the indicator works, sweetie? The indicator works by a REACTION between hydroxide ions and phenolphtalein. Phenolphtalein is colorless, after reacting, it turns purple.
it is the effect of Phemnolpthalein. Although base on the titration, the solution has not reach its end point as the pink did not stay within 30 seconds.
WOWZA!! That was a good titration!! ALthough we know that the addition of a base through a buret to an acid neutralizes the hydrocARBON BONDING OF THE 2,5-dichloro-3-tetramethyl-benzene.
If you want, I can draw up the structural formula later.

Commonly known as a napoleanotic reaction.

is this just water and phenolphthalein?

@UyNj it was three years ago, but I'm pretty sure it was NaOH.. Sodium Hydroxide..

@jessiebm123 acid + base -> salt + water get ur chemistry right.

wow how retarded its not a chemical reaction!!! its an indicator!!!!!

And how is a chemical indicator reacting with a substance not a chemical reaction?
Electric perhaps? ;)
