Write a short note on solid/liquid interface.

Que.: Write a short note on solid/liquid interface.

Ans.:

Adsorption onto the solid surface of molecules dissolved in solution may occur if solute molecules and solid surface have chemical groups capable of interacting. In addition, non-specific or general adsorption may also occur if solute is surface active.

Adsorption from solution is usually more complex than from a gas because of solvent and other components present in the system. Adsorption from solutions may be measured by separation of solid and solution and estimating the amount of adsorbate adhering to solid or the loss in concentration of adsorbate from solution phase.

The solvent can complete for the site of adsorption, it would also determine. escaping tendency of solute i.e., more polar the molecules, less is the adsorption.
