Consumer Products: Acids and Bases
Use a titration to answer one of the following questions
Write a report to summarize your results. Include:
•A paragraph of background on your topic.
•A Step-by-Step procedure, including safety notes.
•A List of any errors, and any problems that occurred, including the solution to those problems, and ways
to minimize the errors.
•Full calculations to answer your question.
•The answer to your question.
*Assume all the acids involved are monoprotic, and all the bases only contain one hydroxide (unless
otherwise stated)
1.Rolaids once ran a national advertising campaign in which it was claimed that Rolaids consumes "fortyseven times its own weight of excess stomach acid". Can this be true? *Assume that stomach acid is
0.100 M HCl and that its density is 1.00 g/mL.
2.Tums once ran a national advertising campaign in which it touted that its product "neutralizes one-third
more acid than Rolaids". Are they lying?!
3.Percent acidity is the basis for determining the legality of vinegar. The percent acid in a sample is
calculated as g/mL x 100. Vinegar is regulated by the Food and Drug Administration (FDA) and must have
a minimum of 5% acidity. The acid involved is acetic acid. I purchased some no name acid at a local
grocery store for a discounted price. Is this vinegar actually 'vinegar', or has it been diluted?
4.It is now possible to purchase low acid apple juice. Does this juice have significantly less acid in it than
regular apple juice?
5.Household ammonia can be purchased as a cleaning product. What is the concentration of the
ammonium hydroxide in it?
6.The active ingredient in Aspirin is acetasalicylic acid. Determine the number of moles of ASA in a tablet
of aspirin. (We cannot determine this using just the mass, since there are many fillers in the tablet.)
7.Are no-name ASA tablet more acidic than Aspirin Brand tablets?
8.The active ingredient in Advil is ibuprofen or 2-(4-isobutylphenyl)propanoic acid. Determine the number
of moles of ibuprofen in a tablet of Advil. (We cannot determine this using just the mass, since there are
many fillers in the tablet.)
9.Are no-name ibuprofen tablet more acidic than Advil brand tablet?
10.Which is more acidic – ASA tablets or ibuprofen tablets?
11.Black tea is acidic because of a mixture of organic acids in the tea leaves. Determine the concentration
of the acid in a sample of tea.
12.What is the concentration of acid in Sprite?
13.What is the concentration of acid in Diet Sprite?
14.Dishwasher detergents are very basic. Determine the concentration of the base in gel dishwasher
detergent.
15.Which has a higher percentage of acid in it – lemon juice or orange juice?
16.Compare the amount of base in a sample of gel dishwasher detergent with the amount of base in a
sample of powder dishwasher detergent.
17.Limewater is a dilute solution of calcium hydroxide. Determine the molarity of the calcium hydroxide in
the limewater. What concentration of carbonate ions must be in the solution for a precipitate of calcium
carbonate to form? (Note: Write the correct formula for calcium hydroxide to determine the number of
hydroxide ions.)
18. How many moles of ascorbic acid are there in 1 vitamin C tablet?
19. Compare different brands of antacids. Which one would neutralize the largest amount of stomach
acid?
