Titration indicator

Question

When titrating HCl with NaOH, is it wrong to use Phenolphthalein?

The titration gives a pH of 7 and that means we won't see any color change?

Answer 1

Phenolphthalein is a commonly used titration indicator, so it isn't "wrong" to use it. You just have to realize that phenolphthalein begins to change from colorless to pink at around pH 8.2, so your endpoint is not exactly the same as your equivalence point (the point at which the HCl is exactly neutralized by the added base). If it is really important to have the observed endpoint of the titration coincide with the equivalence point, use a pH meter.
