Question
You are studying the mineralogy of a soil and have made the following measurements in the lab:
The soil is composed of 64% clay, with 3% organic matter. The soil pH is 6.5. The total soil CEC is 70
cmolc/kg. Using the assumption that the CEC of organic matter is 150 cmolc/kg at pH 6.5. please
determine the most likely kind of clay mineral that is present in the soil sample.
allophane
gibbsite
ilite
O smectite
Cation exchange occurs because cations are bound to soil colloids through
O inner sphere complexes
O cation bridging
pH dependent complexes
outer sphere complexes
