Abstract The pseudo-equilibrium concentrations of the H
, and H
ions, kinetically very important species in the disproportionation reaction of iodous
acid, have been determined from the equilibrium dissociation reactions of sulfuric
and iodous acids in the quasi-stationary state. The values observed were higher than
the concentration of the protonated ion of hypoiodous acid.

Iodous acid, HOIO, an important molecular species, occurs in many complex iodine
reactions. In some systems it undergoes disproportionation. According to previously
published results, the process of disproportionation is very complex [1–5].
General mechanisms of the disproportionation reaction are not yet fully
determined, and complete agreement between reported calculated and experimental
results has not been achieved. Experimental determination of the speciﬁc
