The rate of hydrolysis of methyl and ethyl hydrogen sulphates increases by a factor of 107 when the solvent is changed from pure water to moist dioxan. The reaction is acid-catalysed and the reaction species probably is the zwitterion R-O+H-SO2-O-. The effective strength of sulphuric acid in 98% dioxan-2% water was studied with the indicator p-nitroaniline.
