What (if any) substance can be added to pure water to significantly 
decrease the boiling point of the solution? I know that a mixture of 95.6% 
ethanol and 4.4% water has a constant B.P. of 78.2 degC. But can a chemical 
be added to water and achieve a similar effect? The similar question in 
your archives never actually names a substance.
