dc.description.abstractWe present a novel study of a PbCrO4 Liesegang pattern exhibiting revert spacing. Scanning Electron Microscopy (SEM), Atomic Absorption Spectrometry (AAS) and Energy Dispersive X-ray (EDX) spectroscopy measurements are carried out, and are shown to support the adsorption of CrO42- on the precipitate, which becomes more enhanced as we move farther from the gel interface. Such an ascending differential adsorption scenario favors revert spacing over the direct spacing trend. © 2019 Elsevier B.V.
