Is there any simple way to predict the volume of a second back titration done on a particular antacid substance after completing a titration the first time around?..Thank you every one for responses.

    Yes. IF the first titration was correct AND you know how much of the material was added, it should be no trouble to calculate the amount necessary to back titrate. When I did these, I calculated the volume to be back titrated, stopped about 2 or 3 mL BEFORE, then proceeded with the titration.

    In my titration method it says trial titration. In my table it says rough titration. I know the meaning of both. But, are they the same thing and could i say my first titration rough value is both the trial titration and rough titration?
