Soil chemistry is the study of the Chemistry chemical characteristics of soil . Soil chemistry is affected by mineral composition, organic matter and Environment biophysical environmental factors. History Until the late 1960s, soil chemistry focused primarily on chemical reactions in the soil that contribute to pedogenesis or that affect plant growth. Since then, concerns have grown about environmental pollution , organic and inorganic soil contamination and potential ecological health and environmental health risks . Consequently, the emphasis in soil chemistry has shifted from pedology and agricultural soil science to an emphasis on environmental soil science . Environmental soil chemistry A knowledge of environmental soil science environmental soil chemistry is paramount to predicting the fate, mobility and potential toxicity of contaminants in the environment. The vast majority of environmental contaminants are initially released to the soil. Once a chemical is exposed to the soil environment a myriad of chemical reaction s can occur that may increase or decrease contaminant toxicity. These reactions include adsorption desorption , Precipitation chemistry precipitation , polymerization , solvation dissolution , complexation and redox oxidation reduction . These reactions are often disregarded by scientists and engineers involved with environmental remediation . Understanding these processes enable us to better predict the fate and toxicity of contaminants and provide the knowledge to develop scientifically correct, and cost effective remediation strategies.

unreferenced date July 2009 Wet chemistry is a term used to refer to chemistry generally done in the liquid Phase matter phase . It is also known as bench chemistry because many of the tests performed are done at a lab bench . Materials Traditionally, it involves the use of laboratory glassware , such as beaker s and flask s, and excludes quantitative chemical analysis using instrumentation . Many high school and college laboratories teach students basic wet chemistry methods. History Before the age of Theoretical chemistry theoretical and computational chemistry it was the predominant form of Science scientific discovery in the chemical field. This is why it is sometimes referred to as classic chemistry or classical chemistry . Because of the high volume of wet chemistry that must be done in today s society and quality control requirements, many wet chemistry methods have been automated and computerized for streamlined analysis. Uses Wet chemistry techniques can be used for Qualitative chemical analysis qualitative chemical measurements, such as changes in color colorimetry , but often involves more quantitative chemical measurements, using methods such as gravimetry and titrimetry . Some uses for wet chemistry include tests for pH acidity, alkalinity concentration conductivity electrolytic conductivity Specific Conductance cloud point nonionic surfactants hardness solids or dissolved solids salinity specific gravity density turbidity viscosity moisture Karl Fischer titration Wet chemistry is also used in environmentalchemistry settings and is used for to test Biochemical Oxygen Demand BOD Chemical Oxygen Demand eutrophication coating identification It can also involve the elemental analysis of samples, e.g., water sources, for items like Ammonia Nitrogen Chloride Chromium ... links http www.wcaslab.com photo photwet.htm Wet Chemistry Lab Photo BranchesofChemistry Category Chemistry ar simple Wet chemistry sl Mokra kemija ... more details

The low boiling components tend to evaporate more rapidly, hence they may be removed from the bulk solution containing higher boiling components. It is an alternative to distillation , and it does not require heat. This technique is also used in environmentalchemistry to extract the oil contaminants from subsoil water and the ground. In metallurgy, this process is used to remove dissolved gases from the melt prior to the material being processed. ref Cite book last Degarmo first E.

The resulting argon bubbles will rise to the surface bringing with them a quantity of the dissolved hydrogen. This degassing treatment reduces the occurrence of hydrogen gas porosity .

Product s are formed during chemical reaction s as reagents are consumed. Products have lower energy than the reagents and are produced during the reaction according to the second law of thermodynamics . The released energy comes from changes in chemical bonds between atoms in reagent molecules and may be given off in the form of heat or light. Products are formed as the chemical reaction progresses toward chemical equilibrium at a certain reaction rate , which depends on the reagents and environmental conditions. Depending on the relative amounts of the reagents and the equilibrium of the reaction, the terms reagent and product may also overlap. But in the end, the product is the result of a chemical reaction.
