Where phases meet — adsorption, colloids and chromatography.
At the surface of a solid, molecules stick, separate and scatter light. These simulations explore surface chemistry hands-on: run a paper chromatogram to pull a mixture apart as the solvent front climbs, measure each component's Rf value, and see how the strength with which a substance adsorbs onto the paper decides how far it travels.
Beyond the open showcase, subscribed schools get the growing library of Surface Chemistry experiments — searchable, tagged by concept and difficulty, and expanding continuously.
