Pure sodium aluminate (anhydrous) is a white crystalline solid having a formula variously given as NaAlO2, Na2O Al2O3, or Na2Al2O4. Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. Sodium bisulfate, also known as sodium hydrogen sulfate, is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4.Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically in the form of either sodium hydroxide (lye) or sodium chloride (table salt). It should be noted that at high reaction temperatures such as 80°C and 94°C, the solid readily evolves to a mixture of sodium dawsonite and pseudoboehmite. FTIR spectra corresponding to the solids obtained after heating sodium dawsonite at: (a) 500°C and (b) 700°C. Wie der Name Sodium Laureth Sulfat bereits sagt, handelt es sich bei diesem Inhaltsstoff um ein Sulfat. Sulfate sind Salze oder Ester der Schwefelsäure. Sodium Sulfate has unusal solubility outcomes when in water. On the other hand, the XRD analysis of the solid obtained at pH 10.6 shows the diffraction peaks corresponding to sodium dawsonite NaAl(OH)2CO3 [17]. The curves of these two latter solids correspond to expectations for amorphous basic aluminum carbonate and sodium dawsonite respectively, as determined by FTIR. With Aluminum Sulfate, Sodium Hydroxide can be used to precipitate transition metal hydroxides. Sodium ion is the principal cation of the extracellular fluid and plays a large part in the therapy of fluid and electrolyte disturbances. 1. Next, the flasks were heated at each temperature for various periods of time. the aqueous hydrogen ion i.e. Sodium Sulfate : Annually, 6 million tonnes of Sodium Hydroxide is produced, half from by-products of chemical processes and half from natural sources.

A. Gadsden, “Infrared Spectra of Minerals and Related Inorganic Compounds”, ed. The solubility product constant for barium sulfate is 1.1 x 10-10. It is soluble in acids and alkali, and it’s acidity is 7 therefore it is neutral. In 2004, the worldwide production of Sodium Hydroxide was about 60 million tonnes. Figure 2. The evolution of the chemical structure of the solids heated at 50°C is presented in Figure 7, as determined by FTIR. ... At a pH near to 4.3 there may be oligomers such as Al13O40H487+ or related species that contain sulfate. The strong and broad absorption band centered at 613 cm-1 probably resulted from the combined absorptions of sulfate (ν4), the Al-O stretching vibrations and the Al-OH wagging vibrational mode of molecular water. The comparison of the aluminum 2p peaks, oxide vs metal, after the exposure of aluminum at pH=3.0 for 30 and 1000 min, is indicative of a thicker oxide film after longer solution exposure. A method for preparing sodium aluminate from basic aluminum sulfate (BAS) is presented.

This latter solution was obtained by passing sulfur dioxide through an ammonium hydroxide solution until a solution pH 4 was obtained. The Cosmetic Ingredient Review (CIR) studies individual chemical compounds as they are used in cosmetic products. In the temperature range of 500-700°C the spectra show two absorption bands at 1407 cm-1 and 1524 cm-1 corresponding to carbonate, which was probably absorbed by the solid from the air during the sample preparation. 16. In order to obtain sodium aluminate, sodium dawsonite was heated at different temperatures for 30 minutes and the phase transformation sequence was determined. Auch das Karlsbader Salz, das durch Eindampfen von Karlsbader Mineralwasser gewonnen wird, besteht hauptsächlich aus Natriumsulfat-Decahydrat und wird als Abführmittel eingesetzt.

The TG and DTA curves of sodium dawsonite obtained at 60°C are presented in Figure 10. Support for this hypothesis will be found in the XRD analysis of sodium dawsonite heated at different temperatures. The hydroxide anions make it a strong base which causes it to react with acids to produce water and other salts. The mixture containing aluminum sulfate percents the hides from decaying. 14. Sodium aluminate was prepared by using basic aluminum sulfate as a raw material. The commercial importance of sodium aluminate is due to the versatility of its technological applications. According with thermal analysis curves (TG and DTA), a weight loss corresponding to 36.27% associated with an endothermic peak at 300°C was observed in the temperature range of 100-500°C.
