Over the course of soil development from parent rock to highly weathered soils, mineral weathering reactions occur that alter the surface chemistry of the soil.  Consider the weathering transformation sequence: muscovite/biotite → illite → vermiculite → smectite → kaolinite → gibbsite During the above weathering sequence, what general changes would be expected in following mineral chemical characteristics? Why? (a)  Permanent (structural) charge (b)  pH dependent (variable) charge (c)  Types of surface functional groups (d)  Cation exchange capacity (e)  Anion exchange capacity

A water sample is found to contain Cu but no organic or inorganic ligands except OH-. Assume that only one hydrolysis species contributes significantly to the total Cu in solution.          K        log Kf Cu2++H2O⇌Cu(OH)++H+{“version”:”1.1″,”math”:”Cu2++H2O⇌Cu(OH)++H+”} 10-7.52 -7.52    If [Cutotal] = 10-{T} M and pH = {pH}, what is the concentration of free Cu2+ in the water sample?  Format answer in scientific notation and round to 3 significant figures. Place the order of magnitude (x10^y) in the “units” box with no spaces (D2L doesn’t have a separate spot for this), followed by the units. For example: x10^-4 mol/L.
