Abstract

The effect of gravity on the formation of Liesegang patterns of Ag<sub>2</sub>Cr<sub>2</sub>O<sub>7</sub> in gelatin and that of PbI<sub>2</sub> in agar was investigated. Spatial arrangement of Liesegang bands was measured in the parallel and antiparallel orientation to the gravitational field in a single sample with all other parameters kept fixed. The experimental results are discussed in terms of the prenucleation theory of periodic precipitation. <p>
