Fractional orders such as 3/2 often hint at a chain mechanism. The autoxidation of (H20)5CrCH(CH3) + leads to a number of products. Log (inititd rate) vs log (initial concentration of organochromium cation) plots give a 3/2 slope. The rate is independent of [H+] and [O2] and the rate law is therefore... 

Fig. 9.4 Calculated and experimental solubility of ferrihydrite as a function of pH (Schindler et al., 1963, with permission). The curves were calculated taking into account the species Fe FeOH Fe(OH)J, Fe(OH)4 and Fe2(OH) and the following solubility products (log - Kso) ferrihydrite, freshly precipitated 3.96 ferrihydrite, aged 3.55 and goethite 1.4.

If this constant is combined with the hydrolysis constant log10 j34 = —18.4 for Th(OH)4(aq), a solubility product log]0 X 0(s) = 9.9 for Th02(s) is calculated that lies between the values for Th02(am) and Th02(cr) (see Fig. 4). This set of equilibrium constants now describes the measured solubilities at pH > 6, but fails to account for the solubility variation of more than 10 orders of magnitude at lower pH. 

At room temperature during 2 h, the reaction was conducted with 9.5 g of 2-acetamido-2-deoxy-D-glucose by the same method and procedure [reported in Ref. 96]. After recrystallization of die product (lOg, 90%), the final filtrate was chromatographed on a column of silicic acid (30 g) with 30 1 chloroform/ methanoL...

In the course of a study of nickel ammine complexes, in two experiments turbidity occurred, which was interpreted as an indication of formation of Ni(OH)2. When the solubility product (log,p = -13.8, 25°C) is extrapolated to / = 0 by means of the Davies equation the following constants were obtained (log, X°g= -14.64, log, X" = 13.36) [62DAV]. These values are in line with others which refer to freshly precipitated probably amorphous Ni(OH)2, see Table V-6 [380KA], [54FEI/HAR].

There ate two experimental studies of the solubility of Na6[Th(C03)5]12H20(s) in sodium carbonate and bicarbonate solutions, from Luzhnaya and Kovaleva [1961LUZ/KOV2] and Dervin and Faucherre [1973DER/FAU3]. These studies are discussed in Appendix A. This review has reinterpreted the experimental data and calculated the solubihty product log, K", for the reaction ...

The commercial product contains approx. 75% linear isomer, with approx. 5% branched Isomer and approx. 20% cyclic tetraethylenetetramine. Physical properties given relate to the commercial product. Log P octanol/water Is estimated. Lung edema symptoms usually develop several hours later and are aggravated by physical exertion rest and hospitalization essential. As first aid, a doctor or authorized person should consider administering a corticosteroid spray. Due to its viscosity liquid becomes virtually solid at approx. 10°C. Unbreakable packaging preferred If breakable, keep In unbreakable container. 

Felmy et al, (18) investigated foe solubility of Pu(OH)3 under reducing conditions in deioni water and brine solution. They deriv a much lower solubility product (log K = -26.2) (see Table I) than foe value (log K = -19.6) reported in foe literature (iP). However, foe solubility in brines [I 6 2Uid I - 10] was found to be larger than foat in deionized (I = 0) waters. The solubility of Pu(OH)3 in brines was accurately predicted with foe Pitzer ion-interaction model using only foe parameters for binary interactions between Pu and Cl".
