The acid dissociation constant and hydrolysis rate of hydroxysulfamic acid (HSA) in acid aqueous solutions have been studied. The acid dissociation constant was determined to be K = 1.5 ± 0.5 M at 298 K. The hydrolysis rate, R, was found to be R = k[H+][HSA], where k = 6.2 × 1012 exp (−26 300/RT) M−1 s−1 at (μ = 1.0 M and [HSA] is the concentration of all forms of hydroxysulfamic acid. Keywords: hydroxysulfamic acid, hydrolysis, acid dissociation.
