Soil Chemistry 9-2 Section 9- Oxidation Reduction Eh -pH RELATIONSHIPS Thermochemistry background The Gibbs free energy (G) may be defined in differential form as: dG = - Sd T - V dP - w ′ (1) where w' is defined as the useful work in a chemical system ( non-pressure, volume work) in our case this will be the electrical work of the system.

CHAPTER 1. SOIL PHYSICAL PROPERTIES

Forces acting on soil particle are gravitation, buoyancy and drag forces, and all depend on particle size; The larger particles settle first à Stokes law Since soils are a mixture of different size particles, soil’s are classified using the so-called soil textural triangle.

CARBONATE EQUILIBRIA

Calcium carbonate in water with a fixed partial pressure of carbon dioxide. For the case of a fixed partial pressure of carbon dioxide and calcium carbonate dissolved in the aqueous phase one more equation is need to describe the system. This is the solubility product of calcium carbonate: = K ( CaCO ) ( Ca ) ( CO ) o CaCO 3 2 - 3 2 + 3 (19)

Land,Soil, Water, Natural Vegetation and Wildlife Resources

Water is a vital renewable natural resource. Three-fourth’s of the earth’s surface is covered with water. It is therefore appropriately called the ‘water planet’. It was in the primitive oceans that life began almost 3.5 billion years back. Even today, the oceans cover two-thirds of the earth’s surface and support a rich
