A traditional exercise in quantitative analysis is the titration of mixtures of sodium hydroxide, sodium carbonate, and sodium bicarbonate. Often, consumer products are studied. A procedure to analyze the total volume of carbon dioxide bubbles in the candy "Pop Rocks" is presented. The popularity of the sample and the simplicity of the procedure make this exercise suitable for a wide variety of students: from non-science majors to chemistry majors in a quantitative analysis course.
