Compounds inorganic, being different from organic

At the extreme, inorganic compounds are usually very different from organic chemicals made from non-metals, to be described next, but they may exhibit intermediate and even similar behaviour, as we shall see later in this and subsequent chapters. 

Wohler s synthesis of urea dispelled the notion that organic compounds were fundamentally different from inorganic compounds— and that they could only be produced by nature. We now know that it is possible to synthesize a wide variety of organic compoimds in the laboratoiy in fact, maity thousands of new organic compounds are produced in research laboratories each year. In this chapter, we will consider several types of organic compounds that are important biologically. 

Molybdates yield sparingly soluble orange-yellow molybdyl oxinate with oxine solution the pH of the solution should be between the limits 3.3-7.6. The complex differs from other oxinates in being insoluble in organic solvents and in many concentrated inorganic acids. The freshly precipitated compound dissolves only in concentrated sulphuric acid and in hot solutions of caustic alkalis. This determination is of particular interest, as it allows a complete separation of molybdenum from rhenium. 

A major difference between organic and inorganic hazardous wastes is that, with the exception of cyanide, inorganics cannot be destroyed by being broken down into nonhazardous component parts, because at least one element in the compound is toxic. Inorganic hazardous wastes containing toxic elements can be transformed from a more to a less toxic form, but can never be transformed to a nontoxic form. 

Water is modified by soil when added as either rain or irrigation [2], The modifiers are plants, plant roots, organic matter, organic matter decomposition products, carbon dioxide and other gases in the soil atmosphere, and dissolved inorganic compounds, commonly salts. Of particular importance is the change in pH that accompanies this modification of water. Thus, components obtained from soil by added extraction water will be significantly different from...
