i am about to conduct an experiment on AEO 3,7,9&12 to investigate how does the number of EO chain affects the amount of foam formed. However, i am a little worried that the results will not be very obvious. This is a really big science experiment for me and accounts for a big part of my final grades so i just want to make sure that the results will be visible so that i can comment on it etc. Has anyone did this experiment before? can anyone tell me how would the results look like?
