SSC 100 Additional review questions for exam 2 1. Distinguish between inner sphere and outer sphere complex formation with respect to surface adsorption and cation exchange. 2. What is meant by “K-fixation” by vermiculite? 3. What is meant by “P-fixation” by goethite or gibbsite? 4. How is base saturation calculated? Is base saturation related to soil fertility? Explain. 5. Most acidic soils have Al 3+ as a dominant cation on the cation exchange complex, rather than H + . How does exchangeable Al 3+ result in an acidic soil solution reaction?
