Hi fellow IBs
So, Im doing the redox titration experiment with ascorbic acid and Iodine, the most generic one. I wanna check out what effect high temperatures have on the concentration of vitamin c. Keeping the amount of H2O in the samples is essential, so I use a reflux apparatus to keep the water from evaporating out of the solution. The question is whenever I heat up a juice sample, let's say, to 90?C, do I need to let it cool down before the actual titration process or titrate the sample right away? When I titrated it right away it seemed to me (and it's pretty logical) that the water started to evaporate once poured to a beaker from the reflux.
