Shankar and De Souza have also recently investigated the effect of the additions of various anions to this system in both water and heavy water solvent. Fluoride was found to have very little influence on the exchange rate while acetate, nitrate and sulphate ions produced an increase. For the addition of sulphate ions an estimate of the rate coefficient kj of 20 l.mole . sec (at 14 °C and = 2.0 M) was made. For the addition of nitrate and acetate, values of the coefficients k and kj (where k = k K and kj = k K ), viz. 

Treatment of the complex with further amine produced the violet dyes. The importance of this complex in the mechanism is suggested by the inability of cupric acetate, nitrate or sulphate to achieve the oxidation. 

During preparation of diacetatoplatinum(II) by alternative procedures, the hexahy-droxyplatinate in mixed nitric-acetic acids was evaporated to a syrup and several explosions were experienced [1], possibly owing to formation of acetyl nitrate. On one occasion a brown solid was isolated and dried, but subsequently exploded with great violence when touched with a glass rod. The material was thought to be a mixture of platinum (IV) acetate-nitrate species [2],... 

Photolytic. When synthetic air containing gaseous nitrous acid and 2-methylbutane was exposed to artificial sunlight (X = 300-450 nm), acetone, acetaldehyde, methyl nitrate, peroxy-acetal nitrate, propyl nitrate, and pentyl nitrate were formed (Cox et al, 1980). 

According to their miscibility with water, ionic liquids are also frequently classified as hydrophilic or hydrophobic. The hydrophilic ionic liquids are typically salts composed of halide, acetate, nitrate, trifluoroacetate, and, in some cases, tetrafluoroborate anions, in particular their salts with [AMIM] having short alkyl chains, as these ionic liquids are totally miscible with water. The ionic liquids composed of PF and (CF3S02)2N with [AMIM] are immiscible with water in bulk, and are therefore referred to as hydrophobic ionic liquids. The ionic liquids consisting of BF4 and CFsSOi" ions with [AMIM] can be totally miscible or immiscible depending on the substituents on the cation, and they are therefore sometimes called tunable ionic liquids (22). A recent review covers relevant properties of some ionic liquids for catalysis (42,43). 

Holmium forms all its compounds in -i-3 valence state. The metal forms fluoride, hydroxide, phosphate, oxalate, and carbonate that are insoluble in water. Its water-soluble salts are chloride, bromide, iodide, acetate, nitrate and sulfate. 

Synthetic Membrane Appropriate inert and commercially available synthetic membranes such as polysulfone, cellulose acetate/nitrate mixed ester, or Polytetrafluoroethylene 70 Fm membrane of appropriate size to fit the diffusion cell diameter (e.g., 25 imn in above case). 

The preparation of mixed trimethylolethane esters, i.e. of acetate-nitrates, was described by Marans and Preckel [65], By heating metriol in the presence of metriol triacetate at 175-180°C, a mixture of mono- and diacetate is obtained together with unchanged trimethylolethane. 

The classical qualitative aralysis scheme is based on solubility roles Acetates, nitrates, and chlorides (except For Ag+. Hg. and Pb2 ) are always soluble. There ore specific solubility patterns for sulfides, carbonates, and phosphates. Find a qual scheme and explain it in terms of your unda-sianding of solution processes. 

Anion sensing using visible-emitting lanthanide probes has proven successful (Tsukube et al., 2006) and this work is now being extended to Ybm probes, particularly for the detection of thiocyanate. The latter is the principal metabolite of cyanide anion and exists in human serum, saliva, and urine. The luminescent probe is a complex of hexadentate tetrakis(2-pyridylmethyl)ethylenediamine (tpen, see fig. 119) which bears two water molecules, [Yb(tpen)(H20)2](0tf)3. In absence of anion coordination, the 980-nm luminescence is quenched, but the replacement of the water molecules with thiocyanate or other anions such as acetate, nitrate or halogenides removes the quenching, which makes the complex a responsive probe. The largest effect (a six-fold increase in luminescence) is obtained for thiocyanate, followed by acetate and nitrate (3.5-fold) and chloride (two-fold). 

Barium can also form salts with acetate, nitrate, chloride, and hydroxide ions in soil. The mobility of barium in soils increases upon formation of these water soluble salts (Bodek et al. 1988). In general, the solubility of barium compounds increases with decreasing pH. 

Trivalent chromium compounds, except for acetate, nitrate, and chromium(III) chloride-hexahydrate salts, are generally insoluble in water. Some hexavalent compounds, such as chromium trioxide (or chromic acid) and the ammonium and alkali metal (e.g., sodium, potassium) salts of chromic acid are readily soluble in water. The alkaline metal (e.g., calcium, strontium) salts of chromic acid are less soluble in water. The zinc and lead salts of chromic acid are practically insoluble in cold water. Chromium(VI) compounds are reduced to chromium(III) in the presence of oxidizable organic matter. However, in natural waters where there is a low concentration of reducing materials, chromium(VI) compounds are more stable (EPA 1984a). For more information on the physical and chemical properties of chromium, see Chapter 3.

It should be noted that it is not only preparations of mixed polysaccharides which differ from cellulose in solubility, but also esters (acetates, nitrates) do not dissolve com Jetely m solvents of the corresponding cellulose esters. Thus, the nitrate of mixed polysaccharide(III), which contains 42 mol.-% of altrose, dissolves in acetone to 68%, and the triacetate dissolves in methylene chloride to 65 %.
