The effect of convection on horizontally propagating fronts arising in the acid-catalyzed
reaction of chlorite and tetrathionate ions is investigated experimentally in vertically
oriented narrow reaction vessels of various heights. A stable finger develops which
can be characterized by its mixing length defined as the standard deviation of the
average front profile. The mixing length scales with the height of the reaction vessel,
and the scaling law has been determined for three different chemical compositions.
