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.
