Solfato di ammonio

Descrizione:
Solfato di ammonio, con il numero CAS 7783-20-2, è un sale inorganico composto da ioni di ammonio (NH4+) e ioni solfato (SO4^2-). Si presenta come un solido cristallino bianco ed è altamente solubile in acqua, rendendolo una fonte efficace di azoto e zolfo per le piante. Questo composto è comunemente usato come fertilizzante in agricoltura grazie alla sua capacità di migliorare il contenuto di nutrienti del suolo. Inoltre, Solfato di ammonio è utilizzato in varie applicazioni industriali, inclusa la produzione di additivi alimentari, prodotti farmaceutici e come agente precipitante nei processi di purificazione delle proteine. Ha un punto di fusione relativamente alto ed è stabile in condizioni normali, anche se può decomporsi a temperature elevate. La sostanza è generalmente considerata sicura per l'uso nelle pratiche agricole, ma si deve prestare attenzione ad evitare applicazioni eccessive, che possono portare all'acidificazione del suolo. In generale, Solfato di ammonio è apprezzato per il suo doppio ruolo come fonte di nutrienti e la sua versatilità in vari processi chimici.

  • Reagecon 2M Ammonium Sulphate Double Junction Electrode Filling Solution (Electrolyte)

    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.
