Solutions insoluble

In the United States, Hquid HLW from the reprocessing of defense program fuels was concentrated, neutralized with NaOH, and stored in underground, mild steel tanks pending soHdification and geologic disposal (see Tanks AND PRESSURE VESSELS). These wastes are a complex and chemically active slurry. Suspended in the supernatant Hquid are dissolver soHds which never went into solution, insoluble reaction products which formed in the tank, and salts which have exceeded their solubiHty limit. The kinetics of many of the reactions taking place are slow (years) so that the results of characterization... 

The anodic behaviour of Pb varies depending upon the electrolyte composition and the electrode potential and has been the subject of a number of reviews . In NO,", CHjCOO and BF4" solutions, lead will form highly soluble lead salts whilst in Cl" and 804 solutions, insoluble lead salts are formed when Pb is anodically polarised. 

In determinations of sulphurous acid and sulphites, excess of standard 0.05M iodine is diluted with several volumes of water, acidified with hydrochloric or sulphuric acid, and a known volume of the sulphite or sulphurous acid solution is added slowly and with constant stirring from a burette, with the jet close to the surface of the liquid. The excess of iodine is then titrated with standard 0.1M sodium thiosulphate. Solid soluble sulphites are finely powdered and added directly to the iodine solution. Insoluble sulphites (e.g. calcium sulphite) react very slowly, and must be in a very fine state of division.

Organic matter extracted from earth materials usually is fractionated on the basis of solubility characteristics. The fractions commonly obtained include humic acid (soluble in alkaline solution, insoluble in acidic solution), fulvic acid (soluble in aqueous media at any pH), hymatomelamic acid (alcohol-soluble part of humic acid), and humin (insoluble in alkaline solutions). This operational fractionation is based in part on the classical definition by Aiken et al. (1985). It should be noticed, however, that this fractionation of soil organic matter does not lead to a pure compound each named fraction consists of a very complicated, heterogeneous mixture of organic substances. Hayes and Malcom (2001) emphasize that biomolecules, which are not part of humic substances, also may precipitate at a pH of 1 or 2 with the humic acids. Furthermore, the more polar compounds may precipitate with fulvic acids.

Antifoams can be divided into two groups. The first group includes substances, for which the principle of defoaming action is based on the interaction with the foaming agent resulting in formation of insoluble or poorly soluble compounds. For instance, if soluble calcium or aluminium salts (chlorides) are added to the foaming solution of sodium or potassium salts of fatty acids, or cationic surfactants to anionic surfactants solution, insoluble compounds are formed and the foam is destroyed [6]. The less soluble compound formed, the more efficient the antifoam is.
