Compounds salts

Ammonium Compounds. Salts and hydroxides containing quadricovalent nitrogen are named as a substituted ammonium salt or hydroxide. The names of the substituting radicals precede the word ammonium, and then the name of the anion is added as a separate word. For example, (CH3)4N+I is tetramethylammonium iodide. [Pg.28]

Most of the reactions of the halogens are of the oxidation-reduction type. The halogens are so reactive that they do not occur uncombined in nature and they must be made from halide compounds (salts). We shall consider briefly the preparation of the elements and then explore some of the very interesting chemistry of this family. [Pg.356]

CarrDS. 1981. Lead compounds (salts). In Grayson M, ed. Kirk-Othmer encyclopedia of chemical technology. 3rd ed., Vol. 14. New York, NY John Wiley and Sons, 162, 164, 167, 169. [Pg.499]

Elements on the left side of the periodic table (the metals) react with elements on the right side (the nonmetals) to form ionic compounds (salts). [Pg.131]

As an element, neodymium is a soft silver-yellow metal. It is malleable and ductile. It can be cut with a knife, machined, and formed into rods, sheets, powder, or ingots. Neodymium can form trivalent compounds (salts) that exhibit reddish or violet-like colors. [Pg.284]

Many of the compounds (salts) of neodymium are skin irritants and toxic if inhaled or ingested. Some are explosive (e.g., neodymium nitrate [Nd(NOj)j]). [Pg.285]

A new class of crystalline vanadium(iv) compounds, salts which contain the golden-yellow [V(OR)Cl5] ion, have been prepared by addition of one mole of R OH (R = Me, Et, Pr, or Bu) to a slurry of (NR ) or (pyH )[VClg] in MeCN-Et20. Similar attempts to prepare [V(OR)2Cl4] , however, were unsuccessful. Magnetic moments and e.s.r., electronic, and i.r. spectra of these pentachloroalkoxovanadates are consistent with their proposed formulation. [Pg.43]

Note 3 In some cases the discotic nematic mesophase is formed by compounds that do not have molecules of discotic shape (for example, phasmidic compounds, salt-like materials and oligosaccharides). [Pg.113]

In summary, we can conclude that at moderate salt concentrations typical for seawater ( 0.5 M), salinity will affect aqueous solubility (or the aqueous activity coefficient) by a factor of between less than 1.5 (small and/or polar compounds) and about 3 (large, nonpolar compounds, n-alkanals). Hence, in marine environments for many compounds, salting-out will not be a major factor in determining their partitioning behavior. Note, however, that in environments exhibiting much higher salt concentrations [e.g., in the Dead Sea (5 M) or in subsurface brines near oil fields], because of the exponential relationship (Eq. 5-28), salting-out will be substantial (see also Illustrative Example 5.4). [Pg.164]

Crystallographers grow crystals of proteins by slow, controlled precipitation from aqueous solution under conditions that do not denature the protein. A number of substances cause proteins to precipitate. Ionic compounds (salts) precipitate proteins by a process called "salting out." Organic solvents also cause precipitation, but they often interact with hydrophobic... [Pg.9]

Throughout the 1950s and 1960s, mescaline could be purchased from several chemical supply houses in the form of sulfate or hydrochloride crystals. In 1970, mescaline and peyote were "scheduled as part of a Comprehensive Drug Abuse Prevention and Control Act, which established penalties for possession, manufacture or distribution "a term of imprisonment of not more than 15 years, a fine of not more than 25,000, or both. Title 21 proscribes possession of "all parts of the plant presently classified as Lophophora williamsii, whether growing or not, the seeds thereof, any extract from any part of such a plant, every compound, salt, derivative, mixture or preparation of such a plant, its seeds or extracts. ... [Pg.213]

Pyrosulfurous acid, H2S2O5, is not a stable compound. Salts of the acid are stable and they contain the S2052 ion (sometimes considered as SO2 S032-) that has the structure... [Pg.364]

If present, these modify the functional group(s), e.g., in 3-amino-2-chloro-2-butenoic acid, ethyl ester, hydrochloride. Modifications are used for anhydrides, esters, and salts of acids, oxides, sulfides, and selenides of ring systems containing P and As, hydrazones, and oximes of carbonyl compounds, salts of amines, etc. [Pg.68]

The two most important sources of uranium are the minerals carnotite, where uranium occurs in the hexavalent oxide or hydrated oxide, and pitchblende, where uranium occurs mostly in the tetravalent state as a compound salt with other metals. It also occurs as a mixed oxide with titanium, thorium, and niobium in the tetravalent form. The tetravalent uranium minerals appear to have been geologically formed in the presence of reducing agents such as hydrocarbon minerals, graphite, native metals, and sulfide minerals, while such association is rarely observed with the hexavalent uranium minerals. [Pg.8]
