Using the equivalent millimoles HCl/mg sample, the stoichiometry of reaction of HCl with NaOH (which I know is 1:1), and the molar mass of the hydroxide ion, report the gram equivalent OH- per gram of antacid for each of the three trials.
mass of each tablet-1.211g
HCL+NaOH-->NaCl+H2O
mass antacid Vol HCl(mL) Vol NaOH(mL) mmol HCl/mg sample
#1: 1.314g 25.09 24.58 0.001550
#2: 1.316g 25.07 24.29 0.001582
#3: 1.315g 25.03 24.80 0.001509
I then must convert the gram equivalent OH-/gram antacid to % equivalent OH-.

Solution Summary
This solution details how to find the % equivalent OH- of an antacid. The antacid is treated with acid. The excess acid is then titrated with sodium hydroxide. The volumes of these two solutions are then used to find the neutralizing power of the antacid.
