Homework Help: Chemistry

Posted by Sarah on Tuesday, May 7, 2013 at 1:25pm.

An unknown solid acid is either citric acid or tartaric acid. To determine which acid you have, you titrate a sample of the solid with NaOH. The appropriate reactions are as follows:
Citric acid:
H3C6H5O7 (aq) + 3NaOH (aq) -> 3H2O (l) + Na3C6H5O7 (aq)

Tartaric acid:
H2C4H4O6 (aq) + 2 NaOH (aq) -> 2H2O (l) + Na2C4H4O6

A 0.956g sample requires 29.1 mL of 0.513 M NaOH for titration to the equivalence point. What is the identity of the unknown acid?
