The substance with the lighter molecular weight value (NH 4OH‚ M = 35.0459 g/mole) diffused at a faster rate (dAve = 25.8cm)‚ resulting in the formation of a white ring around the glass closer to the side of the heavier substance (HCl‚ M = 36.4611 g/mole; dAve = 10.8 cm). The agar-water gel set up was composed of a petri
