Titrations:
Do
either Gp I or Gp II-3 antacids
assigned by TA. Obtain data for the other 3 antacids from another group.
Do all 3 as back titrations and 1 as a direct titration (either Tums or NaHCO3,
depending on your assigned group)

Titration data, calculated results
Calculate percent yield as mg HCl required to
titrate/theoretical mg HCl required to titrate x 100%
e=chemical efficiency = percent yield/100
