You Hypothesize That a Tablet of PEPCID AC Can Neutralize

question 9

Multiple Choice

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) 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.
• B) 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.
• C) 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.
• D) 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.
