For a weak acid/strong base titration, if the titration mixture is a dark pink, which of the following is correct? 1. The calculated concentration of weak acid is underestimated because the amount of strong base required to reach and endpoint is underestimated.  2. The calculated concentration of weak acid is overestimated because the amount of strong base required to reach the endpoint is overestimated 3. the calculated concentration of weak acid is underestimated because the amount of strong base required to reach the endpoint is overestimated
