I was doing an Iodine Clock reaction experiment involving hydrogen peroxide and i wanted to know the hydrogen peroxide concentration at a certain point. So I connect a conical flask as the reaction chamber using a water bath and collect gas with a burette. However, the amount of gas found out doesn't resemble on repetitions, so i suspect there are some problems with pressure or other sources. About whether the temperature varies, I 'm not quite sure but since i did the experiment on the same day at room temperature, i think there shouldn't be a lot of variations(especially in an air conditioned room) If you have any queries, could u please send me e-mail and i can attach the experimental setup diagram to u? Looking forward to yr reply.
