In this open ended 45 minute activity, students will measure the amount of citric acid is in a can of lemon lime soda by titration with .100M NaOH. This product includes a) student lab sheet b) student data tables for lab books if you use them and c) teacher instructions.
Your students must already have done some titration of an acid with a base. This lab is open ended in that students are given a bit of background on sodas and citrus sodas in particular and access to equipment and a solution of.100 M NaOH, but no real directions.
My students love this activity because they get to use a process that they’ve learned (titration) on something they know (soda) and feel like they are doing real science.
