Salts sodium sulfate

Glaubersalz, n. Glauber s salt (sodium sulfate decahydrate). 

Explosive dusts can also be changed into mixtures which are no longer explosive by the addition of inert dusts (e.g., rock salt, sodium sulfate). In general, inert dust additions of more than 50 wt % are necessary here. It is also possible to replace flammable solvents and cleaning agents by nonflammable halogenated hydrocarbons or water, or flammable pressure transmission fluids by halocarbon oils. 

Crude Copper Phthalocyanine Blue is stirred in 60% sulfuric acid and the thus obtained sulfate hydrolyzed with water. Subsequent filtration affords the 7-phase. It is also possible to knead crude Copper Phthalocyanine Blue with salt (sodium sulfate), concentrated sulfuric acid, and a third agent, which may be an alcohol, a polyalcohol, or one of the corresponding organic esters [19]. A third option is to stir a-Copper Phthalocyanine Blue with 30% sulfuric acid and glycol monobutyl-ester or the corresponding ethyl ester or tetrahydrofuran [20],... 

Powders. Powders have, in the past, been the principal form in which sulfur dyes were sold. In general, they are made from the dried press cake, finely ground, and standardized with common salt, sodium sulfate, or soda ash. They are prepared for dyeing by making a paste with water, which is dissolved by boiling with the necessary amount of reducing agent and further addition of water. 

Comparison of the salts sodium sulfate and sodium hydrogensulfate. Compare their crystal shapes. Measure the pH of their aqueous solutions. Add magnesium powder to both salts in solution. Add excess dilute hydrochloric acid and barium chloride solution to both solutions.

Acids and bases combine to form compounds which are called salts. Thus the reaction of sodium hydroxide and sulfuric acid produces the salt sodium sulfate, NaoS04 and water ... 

Neutral Soluble Salts. Sodium sulfate and, to a considerably lesser extent, sodium chloride are the principal neutral soluble salts used in laundering compositions. They are often considered to be fillers although they perform an important standardizing function enabling the formulator to manufacture powders of a desired, controlled density. Sodium sulfate, in addition, lowers the critical micelle concentration of organic surfactants and thus the concentration at which effective washing can be achieved. 

Glauber s salt, sodium sulfate decahydrate (Na2S04 IOH2O), undergoes a phase transition (that is, melting or freezing) at a convenient temperature of about 32°C ... 

This is best done by diverting a portion of the main stream and cooling it to crystallize Glauber s salt, sodium sulfate decahydrate. The solubility curve of sodium sulfate in citrate liquor is similar to that in water with the solubility decreasing greatly below about 30 °C. This allows sodium sulfate removal to take place at temperatures readily attained by mechanical refrigeration. 

In France the supply position was worse. By 1776 the political and financial situation there was making the continuity of the imports of ash to that country (particularly from Spain) doubtful, and a prize was offered by the French Academy of Sciences for a new, commercial process in which soda alkali could be produced from common salt. Duhamel s reactions (mentioned earlier) were, of course, completely uneconomical, but it had been established clearly from such studies in pure chemistry that common salt, sodium sulfate, and sodium carbonate were related through the element sodium, and that a commercial process might, therefore, be achieved. It did not prove easy, however, and it was 1789 before Nicolas Le Blanc devised his process (described later) for making alkali from common salt. He did not base his process on the then-current theory of chemical affinity, which suggested that iron should be used to produce alkali from sodium sulfate because of the great affinity of iron for sulfate (13y 14). Indeed, the theory of the precise chemistry of the Le Blanc process remained obscure until about 100 years later, and Le Blanc well...

In this chapter we present iri vitro and vivo norethindrone release rate data (from experiments in which we used the basic salt sodium carbonate and the neutral salt sodium sulfate), discuss the effect of thermal treatment on polymer properties, and finally discuss problems that arise when an extremely water-insoluble drug such as levonorgestrel is used. 

Before the stmctural basis of chemical snbstances became established, compounds were named after people, places, or particular characteristics. Examples are Glauber s salt (sodium sulfate, discovered by J. R. Glauber), sal ammoniac (ammonium chloride, named after the ancient Egyptian deity Ammon from the temple near which the substance was made), and washing soda (sodinm carbonate, used for softening wash water). Today several million compounds are known and thousands of new ones are...

Another common method for moisture removal is by using salts such as sodium sulfate, calcium chloride, magnesium sulfate, calcium sulfate and the like. These salts tend to associate to water molecules to form hydrated salts. Sodium sulfate, for example, tends to clump together when water is present. Sodium sulfate is not suitable for in-cell moisture removal and extraction in ASE. Sodium sulfate can dissolve in hot solvent to a certain extent and can precipitate downstream in...

The term alkali has been largely superseded in chemical conversations by the more general term base , and I shall gradually move towards using that name. An alkali is simply a water-soluble base there are bases that don t dissolve in water, so base is a more general term than alkali . The name stems from the fact that a single compound, the base, can be used as a foundation for building a series of different salts by reaction with a choice of acids. Thus, suppose you take the base sodium hydroxide, then you would get the salt sodium chloride if you neutralized it with hydrochloric acid, the salt sodium sulfate if you used sulfuric acid, and so on.
