CARBONATE EQUILIBRIA - UC Davis

Soil Chemistry5-1 Section 5- CARBONATE Chemistry CARBONATE EQUILIBRIAC arbonates are arguably the most important dissolved component of soil solutions and in alkaline soilsthis statement is even less disputable. Implicit in this statement is the relationship among dissolved carbonatespecies whether or not they are in equilibrium with solid phase metal carbonates . The simplest example ofcarbonates is the control which dissolved carbon dioxide has on water pH and buffering.

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.
