Hi, I am doing a quantitative chemistry experiment for my next assessment and I have to choose between the following 3 experiments: * Comparing commerical antacid tablets and commenting on their effectiveness * Comparing commerical aspirin tablets and commenting on their effectiveness * Comparing commercial fruit juices and commenting on their levels of ascorbic acid (maybe also using different environments they are stored in - i.e. warmer environments promotes oxidation?) These topics all sound good to me, but which one should I choose? I want one which will give me a high mark (assuming I do well) and has lots to talk about - particularly with introductory research, chemistry, chemical concepts etc. Any ideas would be greatly appreciated! Or thoughts to extend any of these investigations too! Thanks!
