Experiment 7: Titration of an Antacid
www.bc.eduthat was neutralized by the antacid is equal to the total number of moles of HCl added minus the number of moles that were neutralized by the NaOH: moles acid neutralized = (moles of HCl added) – (moles of NaOH required for back-titration) = (MHCl x VHCl) – (MNaOH x VNaOH) Eq. 4 where M = molarity and V = volume in liters.

Acid/Base Chemistry: Titration Lab
cpb-ca-c1.wpmucdn.comWhen the acid and base react, they form NaCl (sodium chloride), which is also known as table salt. The titration proceeds until the equivalence point is reached, where the number of moles of acid (H+) is equal to the number of moles of base (OH -). The moles of acid and base are related by the stoichiometry of the balanced equation.
