An experimental apparatus was designed and constructed to use high vacuum and mass spectrometric techniques to determine total and partial vapor pressures above bulk liquid samples in the temperature range between -65C and 25C. Observations on the sulfuric acid-water system revealed complexities which interfered with the experimental goal, but which are of some interest in themselves. These interfering processes included long internal thermal relaxation times and chemical reactions. An unexpected and most interesting observation was an apparent pressure effect on the melting curve of the sulfuric acid-water mixtures.
