Oh oh! Think about pecan pie instead. Crap, now I'm craving some pecan pie. Any luck on how to destract yourself? I may need that info. :D

I don't understand your question as written.

You give two concentrations, 1 M and 3M. The purpose of titration is to find an unknown concentration from a known concentration.

Phenolphthalein is a common acid/base titration indicator and is added to the flask and turns color at the point of concentration.
