An investigation of the kinetics of the iron-catalyzed reaction between the purple-colored, paramagnetic nitrosyl disulfonate (ON(SO3)<sub>2</sub><sup> = </sup>) ions and hydroxylamine monosulfonate (HONHSO<sub>3</sub><sup>---</sup>) ions has been made. [W. J. Ramsey and D. M. Yost, J. Chem. Phys. 21, 957 (1953)]. At a temperature of 20°C, an ionic strength of 0.026, and total added iron concentrations less than 3.5×10^—7 VF, the initial rate of disappearance of ON(SO3)<sub>2</sub><sup> = </sup> is well represented by the equation: [dformula -((d(ON(SO[sub 3])[sub 2] [equals sign] ))/dt) [equals sign] 2{((k[sub 2]h[sub 1](H[sup +]) + k[sub 3]h[sub 1]h[sub 2])/((H[sup +])[sup 2] + h[sub 1](H[sup +]) + h[sub 1]h[sub 2]))}(Sigma Fe[sup +3])(HONHSO[sub 3][sup -]),] where h1 and h2 are the first and second hydrolysis constants for ferric iron and where k2 and k3 are the specific second-order rate constants for the reactions of HONHSO<sub>3</sub><sup>---</sup> with Fe(OH) + + and Fe(OH)<sub>2</sub><sup> + </sup>, respectively. Under the above conditions, and if a value of 3×10^—3 is assumed for h1; h2, k2, and k3 have the values, 7×10^—4 l·mole^—1, 13.7±1.0×10^4 l·mole^—1·min^—1, and 1.5±0.5×10^4 l·mole^—1·min^—1, respectively.
