Question

Calculate the correct boiling point for nitrobenzene. Assume that a total immersion thermometer was used. The obs. boiling point was 205 degree celsius. The reflux ring in the test tube just reached up to the 0 degree celsius mark on the thermometer. A second thermometer suspended along side the test tube at a slightly higher level than the one inside gave a reading of 35 degree celsius.
