That's nothing strange - phenolphthalein fits our rule of thumb that any indicator changing color between pH 4 and 10 will do in the case of not too diluted strong acid. In the case of the diluted acid complete color change is way too far from the equivalence point. Depending on the accuracy needed even the first color change can be occuring a little bit too late.

  • The main issue with phenolphthalein drops is how they work as a pH indicator. When added to a solution, phenolphthalein changes from clear to pink, depending on the pH of the solution. The initial color change from colorless to pale pink happens at a pH of 8.2, and deepens to a dark fuschia as the pH rises to 9.8. If used in a solution with a higher pH, they remain bright deep pink.
