The reaction between nitrite and bisulfite to form hydroxylamine disulfonate has been investigated in weakly acidic solutions (pH 4.5 to 7) and found to consist of three concurrent processes. The reaction rate law can be expressed as d(HADS)/dt = k/sub 0/(H/sup +/)/sup 2/(NO/sub 2//sup -/) + k/sub I/(H/sup +/)(NO/sub 2//sup -/)(HSO/sub 3//sup -/) + k/sub II/(NO/sub 2//sup -/)(HSO/sub 3//sup -/)/sup 2/. The values for the specific rate constants k/sub 0/, k/sub I/, and k/sub II/ (at 295 K and ..mu.. = 1.20) are 8 x 10/sup 5/, 3.8 x 10/sup 3/, and 9.6 x 10/sup -3/L/sup 2//(mol/sup 2/s) respectively. The dependence of the rate constants k/sub I/ and k/sub II/ on temperature and ionic strength were investigated. A reaction mechanism has been proposed which is consistent with these results. The rate constants for the three rate-determining steps in this mechanism have been calculated.
