Comparing Antacids
Question:
Is a generic antacid as effective as a comparable brand-name antacid at neutralizing hydrochloric acid?
Hypothesis:
Rexall will be more effective because it has twice the amount of acid in a smaller solution making it stronger than Tums.
Procedure:
1) Crush 2 small Rexall’s and put in a flask.
2) Crush 1 Tum and put in a flask.
3) Poor 25ml of warm water in each flask.
4) Let flasks sit for 6 minutes and swish around fluids every 20 seconds.
5) Add 5 drops of methyl orange to each flask.
6) Record observations.
7) Add 1ml of NaOH until you see a color change (both flasks are the same color)
8) Record amount of NaOH used for each antacid.
9) The flask that needed the least NaOH is best/more effective.
10) Clean your equipment.
Observations:
Antacid
Color
MCL acid
NaOH
Tums
Merky liquid, yellow
35ml
5ml
Rexall
Yellowish orange
35ml
5ml
Results:
In an experiment to determine whether a generic antacid (Rexall) is affective at reducing heartburn or a brand name antacid (Tums) is more effective, you must first find which one neutralizes the hydrochloric acid in our stomach better.
After creating 2 solutions, one using Rexall and the other Tums (you can see how to do in the procedure) we found that Tums is the more effective antacid.
The methyl orange indicated to us that Tums is more effective since methyl orange turns yellow when it is in a basic environment. In our experiment Tums were more of a pure yellow after 5ml of NaOH was added than the Rexall with equal amounts of NaOH which means that Tums is more effective in reducing acid levels.
Judging by these tests, although Tums may cost you a little bit more, it’s worth it. Why buy a brand that’s not going to do the job well, Tums is better for heartburn.
