What are the main structural factors determining the boiling point of an inorganic compound (See Pauling, Nature of the Chemical Bond, Chapter 2.)... 

Systems of ionic radii were derived almost a century ago, to predict (roughly) interatomic distances in crystals. Today this is no longer necessary, since the structures of practically all binary compounds are already known and easily accessible through databases, so the ionic (as well as covalent) radii are used mainly as standard reference points for interpreting the observed interatomic distances. At the same time, for rough estimations of interatomic distances one can use the standard ionic radii and the corrections in bond lengths for different coordination numbers, derived from the structures of polymorphous inorganic compounds (see Sect. 5.2) ... 

This chapter presents a comprehensive overview of published research on multi-component polymeric systems based on PVA and synthetic polymers or inorganic compounds (see Table 4.1). 

Gaseous elements and inorganic compounds (see the next paragraphs for examples) act as inert inhibitors in the explosion of HN3 organic diluents lead to additional side reactions, which are described on p. 149. The explosion limit of HN3 shifts to higher pressures when the diluent gas pressure is increased at moderate temperatures. The individual hyperbolic curves at low total pressures become linear at higher total pressures [9]. Changing the temperature between 288 and 373 K had only a small effect on the lower explosion limit [63]. 

See Secs. 3.1.2.2 and 3.1.2.8 for naming monatomic and certain polyatomic anions. When an organic group occurs in an inorganic compound, organic nomenclature (q.v.) is followed to name the organic part. 

Inert Gas Dilution. Inert gas dilution involves the use of additives that produce large volumes of noncombustible gases when the polymer is decomposed. These gases dilute the oxygen supply to the flame or dilute the fuel concentration below the flammability limit. Metal hydroxides, metal carbonates, and some nitrogen-producing compounds function in this way as flame retardants (see Flame retardants, antimony and other inorganic compounds). 

Sihcon and boron bum ia fluorine forming siUcon tetrafluoride [7783-61-17, SiF, and boron trifluoride [7637-07-2] respectively. Selenium and tellurium form hexafluorides, whereas phosphoms forms tri- or pentafluorides. Fluorine reacts with the other halogens to form eight interhalogen compounds (see Fluorine compounds, inorganic-halogens). 

Chlorine and Bromine Oxidizing Compounds. The organo chlorine compounds shown in Table 6 share chemistry with inorganic compounds, such as chlorine/77< 2-3 (9-j5y and sodium hypochlorite/7 )< /-j5 2-5 7. The fundamental action of chlorine compounds involves hydrolysis to hypochlorous acid (see Cm ORiNE oxygen acids and salts). 

Because of the toxicity of lead, special care must be taken when working with lead ahoys. Lead and its inorganic compounds are neurotoxias which may produce peripheral neuropathy. Eor an overview of the effects of lead exposure, see Occupational Exposure to Lead, Appendix A (29 CRE 1910.1025) (see... 

Plants can also be pests that need to be controlled, particulady noxious weeds infesting food crops. Prior to 1900, inorganic compounds such as sulfuric acid, copper nitrate, sodium nitrate, ammonium sulfate, and potassium salts were used to selectively control mustards and other broadleaved weeds in cereal grains. By the early 1900s, Kainite and calcium cyanamid were also used in monocotyledenous crops, as well as iron sulfate, copper sulfate, and sodium arsenate. Prom 1915 to 1925, acid arsenical sprays, carbon bisulfate, sodium chlorate, and others were introduced for weed control use. Total or nonselective herbicides kill all vegetation, whereas selective compounds control weeds without adversely affecting the growth of the crop (see Herbicides). 

Sulfuric acid, H2SO4, the most important commercial sulfur compound (see Sulfuric acid and sulfur trioxide), and peroxymonosulfuric acid [7722-86-3] (Caro s acid), H2SO, are discussed elsewhere (see Peroxides and peroxide compounds, inorganic). The lower valent sulfur acids are not stable species at ordinary temperatures. Dithionous acid [15959-26-9] H2S2O4, sulfoxyHc acid [20196-46-7] H2SO2, and thiosulfuric acid [13686-28-7] H2S2O2 are unstable species. A discussion of efforts to isolate and characterize the unstable sulfur acids is given (330).

Much confusion exists concerning the number, composition, and structure of the oxides of lead. PbO exists as a red tetragonal form (litharge) stable at room temperature and a yellow orthorhombic form (massicot) stable above 488°C. Litharge (mp 897°, d 9.355 gcm ) is not only the most important oxide of Pb, it is also the most widely used inorganic compound of Pb (see Panel on p. 386) it is made by reacting molten Pb with air or O2 above 600° and has the SnO structure (p. 383, Pb-O 230 pm). Massicot (d 9.642 gcm ) has... 

Discussion. Potassium nitrate is an example of an inorganic compound which absorbs mainly in the ultraviolet, and can be employed to obtain experience in the use of a manually operated ultraviolet/visible spectrophotometer. Some of the exercise can also be carried out employing an automatic recording spectrophotometer (see Section 17.16).
