Resumen:
We experimentally study the development of cellular acidity fronts during the chlorite oxidation of tetrationate performed in a thin layer of viscous solution containing different amounts of polyelectrolyte. These properties and the interaction between fronts are investigated as a function of initial chemical concentrations. The observations are compared to numerical results obtained with a skeleton kinetic model of the reaction using a two-dimensional finite element integration scheme. The agreements with observations are striking.
