Gathered here are those chemical properties which are not covered under the general headings of phase equilibria and crystal structure. The chemical properties of a feldspar can be considered from many viewpoints: thus a crystal chemist emphasizes the chemical bonding, whereas a geochemist emphasizes th...
The nutrient concentration of manure ash was dependent on the reduction rate of solid materials by incineration. The phosphorus (P) and potassium (K) of cattle and layer manure were not concentrated greatly because of high silicon (Si) and calcium (Ca) concentrations, respectively. On the other...
whitephosphorusunites readily with iodine. The iodideionis a strong reducing agent; that is, it readily gives up oneelectron. Although theiodide ion is colorless, iodide solutions may acquire a brownish tint as a result of oxidation of iodide to free iodine by atmosphericoxygen. Molecules of ...
