CAS 7783-20-2
:Sulfate d'ammonium
Description :
Sulfate d'ammonium, avec le numéro CAS 7783-20-2, est un sel inorganique composé d'ions ammonium (NH4+) et d'ions sulfate (SO4^2-). Il se présente sous la forme d'un solide cristallin blanc et est hautement soluble dans l'eau, ce qui en fait une source efficace d'azote et de soufre pour les plantes. Ce composé est couramment utilisé comme engrais en agriculture en raison de sa capacité à améliorer la teneur en nutriments du sol. De plus, Sulfate d'ammonium est utilisé dans diverses applications industrielles, y compris la production d'additifs alimentaires, de produits pharmaceutiques et comme agent précipitant dans les processus de purification des protéines. Il a un point de fusion relativement élevé et est stable dans des conditions normales, bien qu'il puisse se décomposer à des températures élevées. La substance est généralement considérée comme sûre pour une utilisation dans les pratiques agricoles, mais il convient de faire attention à éviter une application excessive, ce qui peut entraîner une acidification du sol. Dans l'ensemble, Sulfate d'ammonium est apprécié pour son double rôle en tant que source de nutriments et sa polyvalence dans divers processus chimiques.

CAS :Reagecon's 2M Ammonium Sulphate (NH₄)₂SO₄ Double Junction Electrode Filling Solution must be used in the outer chamber of a double junction reference electrode for pH or ion measurement, in situations where Potassium Chloride or Potassium Nitrate should not be used. Chloride (Cl-) anions can form insoluble precipitates with Hg++, Cu++, Ag+ or Pb++ which will block the diaphragm of a single junction reference electrode. Potassium may react with anions such as perchlorate (ClO₄¯) to form Potassium Perchlorate (KClO₄). In these situations Reagecon's 2M Ammonium Sulphate Double Junction Electrode Filling Solution is an ideal compromise. - A good electrolyte must fulfil a number of conditions. The equitransference of the cation/anion combination should be as close as possible to being equimobile, have constant chloride activity, be of high electrical conductance and be as non-chemically reactive as possible. Reagecon 2M Ammonium Sulphate Double Junction Electrode Filling Solution is a high quality product that fulfils most of these criteria. However, as outlined above the use of Chloride or Potassium in the electrolyte is precluded for certain types of samples. In such instances Reagecon 2M Ammonium Sulphate Double Junction Electrode Filling Solution, is an ideal substitute.Couleur et forme :LiquidAmmonium Sulfate
