Get a sample of the antacid tablet that contains calcium carbonate
Measure 1.00 g of the antacid tablet into a 50-mL graduated cylinder.
Measure 50 mL of 0.5 M NaOH (aq) and pour it into a 50-mL buret.
Get the antacid in a beaker and add 25 mL of 1.0 M HCl to help dissolve it.
Add four drops of Bromothymol Blue (pH range 6.0-7.6) to the current antiacid + 1.0 M HCL solution. The solution should turn a light yellow. 
Add the 0.5 M NaOH (aq) to the current  antiacid + 1.0 M HCL + Bromothymol Blue solution  and stir with rod by titrating 1 mL at a time)
Monitor the pH of the solution using Bromothymol Blue by titrating with the 0.5 M NaOH (aq) until the solution turns a light green color that doesnt go away when stirred, which means it has reached its equvalence point, and means that the reaction has completed. 
Measure the total volume of 0.5 M NaOH (aq) that was added to the antacid tablet/1.0 M HCl solution.
Calculate the moles of hydrochloric acid that can be neutralized by the antacid tablet.

So In lab here is the data I collected:
 Total volume of of 0.5 M NaOH (aq) added 37.5 mL
NAME_1 of tablet used: 1.0015 Provide response in all capital letters, no lowercase letters allowed.
