Sodium dodecyl sulphate (SDS) solubility. Follow all instructions you have been given closely. Sodium lauryl sulfate (C12H25SO4Na) is a surface-active agent used in cleaning and cosmetic products. Laboratory Studies. Authors: Hans-Jürgen Schwarz , Michael Steiger, Tim Müller, Amelie Stahlbuhk Experimental measurements of the solubility of sodium sulfate in aqueous solutions containing both sodium chloride and sulfuric acid in the temperature range 250 to 374°C are reported. Salts, basic, such as HEXADECYL SULFATE, [SODIUM SALT], are generally soluble in water. C. It complies with the test for loss on drying (see Tests). Anhydrous sodium sulfate is hygroscopic. The decahydrate mirabilite is stable below 32.4 °C. In fact, in pure methanol, sodium sulfate was essentially insoluble. Use powder, alcohol-resistant foam, water spray, carbon dioxide. Sodium sulfate should be kept in a well-closed container. At Alibaba.com, you can buy countless sodium sulfate solubility at good prices. Each of these forms appears as a white crystalline solid. Its density is 2.66 g/cm³. The addition of more heat facilitates the dissolving reaction by providing energy to break bonds in the solid. At this point the solubility curve changes slope, and the solubility becomes almost independent of temperature.  Its solubility in water rises more than tenfold between 0 °C to 32.384 °C, where it reaches a maximum of 497 g/L. It is considered one of the main chemicals marketed. Write a short note on the solubility of sodium sulphate in water At a temperature of 0 degrees celsius, the solubility of anhydrous sodium sulphate in water is 47.6 grams per litre. Rard, J. The presence of methanol was observed to reduce the solubility of the salt greatly. Articles of sodium sulfate are included as well. NO open flames. This temperature of 32.384 °C, corresponding to the release of crystal water and melting of the hydrated salt, serves as an accurate temperature reference for thermometer calibration. The solubility of the phases depends on the temperature. EC Number: 231-820-9 EC Name: Sodium sulphate CAS Number: 7757-82-6 Molecular formula: H2O4S.2Na IUPAC Name: disodium sulfate Also the saturated solution densities were measured. Solubility Freely soluble in water. Additional information. Chemsrc provides sodium sulfate(CAS#:7757-82-6) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Among those salts, sodium sulfate has been found to be particularly damaging [4–6].
