Chemistry · Surface Chemistry
The variation of surface tension of three different aqueous solutions with increasing concentration of solutes (surfactant, sodium chloride, and n-propanol) shows three distinct behaviors: (I) sharp decrease at low concentration reaching a minimum, (II) small linear increase, and (III) continuous non-linear decrease. Match these behaviors (I, II, III) with the correct solutes.
