Lab: Titration of NaOH (0.1 molar)to unknown solid acid. Trying to determine the equilivent weight of the unknown acid in the experiement.

I am trying to figure out if I add too much base solution by accident to an unknown acid during titration would it affect the equivalent weight of the acid?

    You don't have enough information for me to give a quantitative answer; however, the answer to your question is YES, it will affect the equivalent weight of the acid.

    if you over titrate, you should be able to correct with a titration of a standard acid

    if you think you may have added too much, the amount of the unknown acid will appear to be more than it actually is
    __ this would cause you to think you have more moles, so the equivalent weight that you calculate would be too low
