Product Details

Oh, my aching head! I need some pain reliever, but which brand of aspirin should I take? Students will: • Experimentally determine the aspirin content of three brands of over-the-counter pain relievers using acid-base neutralization titration techniques and then compare the amounts to those listed on the bottle. • Compare the effects of regular, buffered, and enteric-coated aspirin on a “simulated stomach.” • Compare the actual amount of aspirin and cost-effectiveness of each tablet and then make comparisons and draw conclusions about different brands of aspirin. • Learn the history and chemistry of aspirin as well as about the different types on the market with the extensive background material. Teacher Notes and reproducible student handouts included. All aspirin samples, chemicals, and specialized equipment are provided in the kit. Complete for 30 students working in pairs.
