Abstract

A number of nitrogen sulfonates are produced by reactions between bisulfite ions and nitrite ions in aqueous solution. Thus, their chemistry is of interest in studies of aqueous aerosols in polluted air and in wet flue gas scrubbing systems. The hydrolysis reactions of nitridotrisulfate (NTS) and hydroxysulfamate (HSA), have been thoroughly investigated. Sisler and Audrieth observed the hydrolysis reaction of NTS at several temperatures: N(SO/sub 3/)/sub 3//sup 3 -/ + H/sub 2/O ..-->.. HN(SO/sub 3/)/sub 2//sup 3 -/ + H/sup +/ + SO/sub 4//sup 2 -/. They found that the NTS hydrolysis reaction occurred much more quickly than the iminodisulfate hydrolysis reaction but did not obtain any quantitative results. The authors have studied the hydrolysis of NTS over a temperature range of 283-333 K at solution pHs ranging from 4.1 to 6.7. The influence of ionic strength was determined over a range of ..mu.. = 0.03-0.5 M.
