A student carried out a simple distillation of toluene for purification. Gas Chromatography analysis indicated the obtained fraction was 100% pure. Nevertheless, the thermometer reading for the distillate by that student was 95 degrees celsius for the fraction, which indicated it was impure. What error do you think the student made?
