Chооse ONE оf the following questions to аnswer. Answering both will not аllow you to eаrn extra points. Option 1 In addition to mineral weathering, soil pH typically declines over time in warm, moist environments. a. What effects would this have on CEC and AEC? b. Draw a diagram explaining why CEC and AEC change with a decrease in pH. Your diagram should have at least 2 parts: low vs high pH. Adding a medium pH portion is optional. c. Add diagram labels (or a description) to explain what is happening in terms of PZC and pKa. Use arrows to show if the pKa and/or PZC labels apply to just a functional group, or the whole surface. Option 2 Explain how each of the following factors influence sorption & bioavailability of metal cations: Soil/sediment (sorbent) properties: overall PZC, functional group pKa's, %organic matter, types of minerals (name specific types of clays, oxides and/or hydroxides) Metal (sorbate) properties: charge, hydrated radius, water exchange rate or pKh
