PbO PbO H2O, for example, may be formed by boiling suspensions of lead oxide and lead sulfate in water. In addition, complex mixed salts, such as white lead, 2PbC02 Pb(OH)2, are readily formed. 

Electroplating. When ionicaHy bonded molecules are dissolved in a solvent, some of the molecules dissociate into ions, whether the solvent is water, organic solvent, or a fused salt. A simple example is that of sulfuric acid or copper sulfate in water, giving... 

Hydroperoxy-lanostenyl acetate The sample solution is applied and then treated with 5% iron(II) ammonium sulfate in water — methanol — ether (2 -t-1 -t-1) 11-Oxolanostenyl acetate is formed [34]... 

To a solution of 0.5 g of lithium aluminum hydride in 35 ml of ether is added 0.2 g of the A -cyanoaziridine. The mixture is heated at reflux temperature for 3.5 hr, cooled, and treated with excess saturated sodium sulfate in water. Filtration and evaporation of the ethereal filtrate gives 0.18 g of a glass which is chromatographed on 10 g of basic alumina (activity III). The benzene-petroleum ether (1 3) eluate gives 0.12 g of 2a,3a-imino-5a-choles-tane, mp 117.5-118.5°, after crystallization from methanol. 

Magnesium is reduced from a mixture of magnesium, calcium, and sodium chlorides. Electrolysis from aqueous solution is also possible zinc, copper, and manganese dissolved as sulfates in water can be reduced electrolytically from aqueous solution. 

The saturated solution of silver sulfate in water at 25°C has a molality equal to 0.02689, and the activity coefficient y of tho solute in this saturated solution is 0.533.

A saturated solution of silver sulfate at 25°C can be prepared by dissolving 1.2gof silver(I) sulfate in water to make 250.0 mL of solution. What is f p for silver(I) sulfate ... 

Calculate the solubility, in moles per liter, of calcium sulfate in water, using the solubility product given in Table 10-11. 

In an electrochemical study of the behavior of the counterions in the mixed cation systems sodium and silver, sodium and calcium, and silver and calcium containing the dodecyl sulfate anion, Corkill and Goodman [102] determined the CMC of sodium, calcium, and silver dodecyl sulfates in water and in solutions of sodium and silver nitrate. 

The aggregation numbers of alcohol sulfates can be as low as 20 for sodium octyl sulfate in water solution but usually range from 60 to 150 for higher alcohol sulfates. 

Sodium aluminate, NaAl(OH)4, is used along with aluminum sulfate in water purification. When mixed with aluminate ions, the acidic hydrated Al3+ cation from the aluminum sulfate produces aluminum hydroxide ... 

Solid phase micro extraction (SPME) is a techniques in which a silica fiber coated with a thin film of polymer is brought into contact with an aqueous matrix where the organics in solution partition onto the fiber. The fiber is subsequently placed into the injector of a GC where the heat causes the release of analyte onto the column. This has been applied to endosulfan (a- and (3-) and endosulfan sulfate in water with limits of detection of less than 0.3 pg/L reported (Magdic and Pawliszyn 1996). 

GC/ECD or a halogen-specific detector (HSD) (Method 8080) is the technique recommended by EPA s Office of Solid Waste and Emergency Response for determining a- and [3-endosulfan and endosulfan sulfate in water and waste water at low-ppb levels (EPA 1986a). At these low concentrations, identification of endosulfan residues can be hampered by the presence of a variety of other pesticides. Consequently, sample clean-up on a Florisil column is usually required prior to analysis (EPA 1986a).

Nitrophenylpyruvic acid was reduced to oxindole using iron pin-dust-ferrous sulfate in water. The iron oxide-iron residues, after filtering and washing with chloroform, rapidly heated in contact with air and shattered the Buchner funnel [1], Previously, rapid heating effects had been observed on sucking air through the iron oxide residues from hot filtration of aqueous liquor from reduction of a nitro compound with reduced iron powder [2],... 

In the reduction of C-C triple bonds with chromous sulfate in water, the key intermediate consists of a dichromium complex with the alkyne (Scheme 20.29) [119]. This configuration assures the selective formation of trans double bonds. Various substrates have been reduced in excellent yields without the occurrence of isomerizations or byproduct formation (Table 20.4).

Dissolve 5 g. of cadmium sulfate in water, add about 5 cc. of ammonia, and precipitate the cadmium sulfide by a current of hydrogen sulfide. Wash the precipitate with pure water repeatedly (by decantation). Suspend it in pure water and conduct into the suspension a rapid current of hydrogen sulfide. The precipitate at first assumes a milky appearance and finally disappears. Boil the sol until the excess of hydrogen sulfide is driven off.
