3. Compare montmorillonite, hydrous mica, vermiculite, chlorite, kaolinite, and the sesquioxides of iron and aluminum, as to: a. Cation exchange capacity b. relative swelling when moistened c. relative degree of stickiness when wet d. environmental conditions where predominant Solution
(a)Montmorillonite -(cation exchange capacity)-CEC meq/100 g=60–100,
Hydrous Mica-(cation exchange capacity)-(surface charge cmolc/kg-1)=10 - 40 ,
Vermiculite-(cation exchange capacity) (surface charge cmolc/kg-1)=100 to 200,
Chlorite-(cation exchange capacity) (surface charge cmolc/kg-1)=10 to 40,
Kaolinite-(cation exchange capacity) (surface charge cmolc/kg-1)=1 to 15,
Sesquioxides-(cation exchange capacity) (surface charge cmolc/kg-1)=0–3,
(b)Montmorillonite-(Water swelling capacity)-high,
Hydrous Mica-(Water swelling capacity)-low,
Vermiculite-(Water swelling capacity)-high,
Chlorite-(Water swelling capacity)-none ,
Kaolinite -(Water swelling capacity)-almost none,
Sesquioxides -(Water swelling capacity)-low,
