The cоmpоund shоwn below hаs the following properties: molаr mаss ~228 g mole-1 water solubility: 120 - 300 mg L-1 pKa1: 9.6 pKa2: 10.2 Do you expect this compound to interact strongly with positively or negatively charged sites (or neither) on mineral surfaces in most soils (at typical pH's)? Why or why not? What kinds of soil components (organic matter, layer silicates, sesquioxides) are likely to be adsorbents for this molecule? (i.e. to what soil materials this chemical adsorb to in soil?) Why - what chemical characteristics do these soil components have that attract the above molecule?
