כטןεБӘЛ(b) Adsorption of a solute can take place from the liquid surface to a solid surface when thesolution is treated with a solid. Assuming that the solute adsorbs strongly compared to thesolvent, sketch comparative qualitative plots of x/m (amount adsorbed /g) vs C (concentrationin solution) for the individual adsorption of ethyl, n- propyl and n-butyl alcohols from anaqueous solution to a hydrophilic silica sample. Give suitable explanation for the plots. (2)
