part d calculate the moles of acid added to the sample. calculate the moles of base added to neutralize the excess acid. calculate the moles of acid that were neutralized by the portion of tablet. use the moles of acid neutralized by the portion of tablet to calculate the moles of acid that could be neutralized by the entire antacid tablet. report the average and the standard deviation. compare the number of moles determined experimentally to the number of moles predicted to be neutralized by the amount of active ingredient in the tablet. (you will need to write the balanced chemical equation using hydrochloric acid and the active ingredient.)
