Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.

Can phenolpthalein solution be used to prove that toothpaste is a base?
Phenolphthalein changes from colorless to pink in the range of pH 8.2 - 10. If toothpaste has a pH that is below this range, phenolphthalein will not indicate the basicity. if the pH is higher, which I believe it is in most (some) toothpastes, then phenolphthalein can be used, because it will turn from colorless to pink.
What color does phenolpthalein turn in the presenc of an acid?
Phenolphthalein only gives colour to bases with a pH above approximately 8.2-10. Then it gives a pink colour. As HCL is a strong acid it becomes colourless.
