As already pointed out, some of the products of periodate oxidation, especially the mixed acetals from the glycosidic derivatives of the sugars, are readily hydrolyzed by acids. Although the known compounds of this type are stable in dilute aqueous solution of iodic acid at room temperature, heating the acid solution would be expected to cause hydrolysis. Before isolation of these oxidation products, the reaction solution customarily is neutralized to a pH of 8-9. Barium hydroxide and strontium hydroxide have proved to be advantageous bases for neutralization of the reaction solution, since iodate and excess periodate are largely removed at the same time as the slightly soluble barium or strontium salts. Silver acetate and hydriodic acid also have been used to remove iodic add.128... 

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. 

Ba Srj TiOj is synthesized, barium and strontium carbonates or acetates are dissolved in the aqueous solution containing water-soluble titanium complex. Although strontium salts can be dissolved in water relatively easily (there are numerous water-soluble strontium salts), strontium forms precipitate with citric acid that is hardly soluble in water. Therefore to utilize citratoperoxotitanium complex for the synthesis of Ba Srj. Ti03 is difhcult. In such a case, the com-plexing agent should be changed. 

Why does hydrochloric acid differ from acetic acid in its action with calcium oxalate (4) Why does acetic acid differ in the action with calcium oxalate and barium oxalate (5) How may a soluble calcium salt be distinguished from a barium or strontium salt ... 

Casein which is a phosphoprotein, is the chief nitrogenous constituent of milk, in which it occurs as a calcium salt in combination with calcium phosphate. Casein is insoluble in water, but its salts are readily soluble those of calcium, barium, strontium, and magnesium form opalescent colloidal solutions. The sodium, potassium, and ammonium salts form comparatively clear solutions, which pass through clay filters. Casein also forms salts with acids. It is precipitated from a solution of its salts and from milk by small quantities of mineral acids, and by larger amounts of acetic acid, but it dissolves in an excess of acid. Casein and its salts are precipitated from solutions by saturating the latter with sodium chloride, magnesium sulphate, or sodium sulphate. The solutions of the salts of casein...

Alkali metal and alkaline earth metal salts of AzTZ are mostly soluble in water with the exception of the barium and strontium salts that are almost insoluble [89]. The potassium salt is hardly soluble in cold water, but more soluble in hot water [2]. The mercury and lead salts are also almost insoluble [90]. The lead salt is insoluble in inorganic solvents but soluble in weak acids and bases. The monobasic salt is insoluble in water and slightly soluble in most organic solvents. The best solvent for this salt is diluted nitric acid or a solution of ammonium acetate [2]. 

Resoles are usually those phenolics made under alkaline conditions with an excess of aldehyde. The name denotes a phenol alcohol, which is the dominant species in most resoles. The most common catalyst is sodium hydroxide, though lithium, potassium, magnesium, calcium, strontium, and barium hydroxides or oxides are also frequently used. Amine catalysis is also common. Occasionally, a Lewis acid salt, such as zinc acetate or tin chloride will be used to achieve some special property. Due to inclusion of excess aldehyde, resoles are capable of curing without addition of methylene donors. Although cure accelerators are available, it is common to cure resoles by application of heat alone.

The hydrolytic ability of hydrochloric acid may be affected by salts present in the reaction mixture. The effect may be based on salting out of the hydrolysis products from the reaction mixture. For instance, magnesium and ammonium sulfates showed such an effect.117 Zinc and cadmium cations, as well as acetate and sulfate anions, decreased the hydrolysis rate with 0.1 M hydrochloric acid, whereas calcium, strontium, and barium ions exerted no effect.141 Neither copper metal, stainless steel, tin, nor sulfur dioxide impeded the hydrolysis with a solution of 0.03-0.05 M hydrochloric acid.142 There is a report143 that traces of metal salts affect the rate of hydrolysis but there are also contradicting findings144 145 that...
