Introduction
The capability of three distinct antacids for stabilization was performed.
One out of the three antacids had to prove to stabilize more than the other antacids. The results of
the experiment will obtain outcome from an acid/base titration. Each of the three antacids will be
evaluated with two trials for each. Figure 1,2, and 3 will provide the results for Alka-Seltzer,
Tums, and Milk of Magnesia. The results of the experiment should provide with evidence with
antacid prescribed is more promising.

Procedure
The proper attire (apron, gloves, and goggles) was needed to perform the experiment. The
balance was reset to weigh 5 g of acetic acid on a large cup. Water (20 mL) was also measured
but on a graduated cylinder (50 mL). The water measured was added to the large cup that
contained acetic acid. They were mixed thoroughly with six drops of Bogen’s universal indicator.
When the liquids were all mixed one tablet of Alka-Seltzer was weighted and added. When the
tablet of Alka-Seltzer was fully dissolved sodium hydroxide (10 mL) was added.
