Wave profile in the acidic nitrate–ferroin reaction
Abstract
The spatial concentration profile of the autocatalytic wave in the acidic nitrate–ferroin reaction has been investigated by a home-built two-dimensional spectrophotometer as a function of the initial reactant concentrations. The formula [graphic omitted] ≈ 0.36 (k1/D)1/2[H+]1/20[Fe(phen)2+3]0, obtained on the basis of a simplified mechanism of the reaction gives a fairly good description of the experimentally found slope of the wave profile at the inflection point.
