Hi everyone, I'm currently searching for chemistry ia ideas. My initial idea had to do with caffeine extraction from tea by titration, however I'm really confused about the method. I've mostly found procedures involving chloroform, which I will however not be able to use for my lab. I also came across a method that uses iodometric back titration, but there doesn't seem to be much info about it online... Does anyone have experience with this method, or has done their ia on a similar topic? I'm really interested in it but I'm concerned that it's way too complicated (i'm in chemistry sl and we haven't done any practicals during ib year 1 due to covid, so i'm looking for something relatively simple to do in my ia). My other ideas included determining the effect of steeping time on acidity of tea / determining the effect of cooking temperature on the stability of cooking oils / determining the effect of temperature on water hardness - are any of these maybe better? Also, if anyone has some fairly simple topic ideas (preferably linked to titrations), I'll be really grateful! I would appreaciate any advice!!:)
