You've been experiencing acid indigestion lately, and you'd like a quick fix for the problem. you do a little research on the internet and discover that your problem is caused by excess stomach acid. in the pharmacy aisles, however, you're having a little trouble deciding what to purchase to address the problem. at the pharmacy counter, the clerk recommends that you purchase pepcid ac or alka-seltzer tablets.
you hypothesize that a tablet of pepcid ac can neutralize more stomach acid than a tablet of alka-seltzer. if you placed a tablet of each antacid in a beaker of acid at an initial ph of 2, which of the following experimental results would support your hypothesis?
a. it took 3 minutes for the pepcid ac tablet to fully dissolve and it took 5 minutes for the alka-seltzer tablet to fully dissolve.
b. after 1 hour, the ph of the solution in the pepcid ac beaker was equal to that of the ph of the solution in the alka-seltzer beaker.
c. after 1 hour, the ph of the solution in the pepcid ac beaker was 7.9 and the ph of the solution in the alka-seltzer beaker was 9.6.
d. after 1 hour, the ph of the solution in the pepcid ac beaker was 9.2 and the ph of the solution in the alka-seltzer beaker was 8.3
