CAS 7664-38-2: Acido fosforico
Descrizione:
Acido fosforico, con il numero CAS 7664-38-2, è un liquido incolore, inodore e viscoso che è altamente solubile in acqua. È un acido triprotico, il che significa che può donare tre protoni (ioni H⁺) in soluzioni acquose, risultando in un pH che può variare significativamente a seconda della concentrazione. Acido fosforico è comunemente usato in fertilizzanti, aromatizzanti alimentari e come rimuovi ruggine grazie alla sua capacità di reagire con ossidi metallici. Ha una tossicità relativamente bassa rispetto ad altri acidi, ma può comunque causare irritazione alla pelle, agli occhi e alle vie respiratorie al contatto. La sostanza è igroscopica, il che significa che può assorbire umidità dall'aria, e ha un punto di ebollizione relativamente alto rispetto a molti altri acidi. In termini di reattività chimica, Acido fosforico può partecipare a varie reazioni, inclusa l'esterificazione e la neutralizzazione, rendendolo un composto versatile sia in ambienti industriali che di laboratorio. La sua capacità di formare fosfati è cruciale nei sistemi biologici, in particolare nei processi di trasferimento di energia come l'ATP.

CAS:Phosphoric acid is used mainly in fertilizers. It is used as an external standard for phosphorus-31 Nuclear magnetic resonance (NMR); as an electrolyte in phosphoric acid fuel cells and as a catalyst in the hydration of alkenes to produce alcohols, predominantly ethanol. It finds application as a buffer agent in biology and chemistry; as a solution for anodizing and as a cleaner by construction trades to remove mineral deposits, cementitious smears and hard water stains. It is also used as a pH adjuster in cosmetics and skin-care products and a dispersing agent in detergents and leather treatment. It plays an important role in the preparation of albumin derivatives. It is an important starting material used in the preparation of disodium hydrogen phosphate, trisodium phosphate, calcium dihydrogen phosphate and monohydrogen phosphate. It is also used in dentistry and orthodontics as an etching solution as well as a sanitizing agent in dairy, food and brewing industries. It serves as an acidic fruitlike flavoring in food products. It is widely used to remove rust in steel tools or surfaces by converting the rusted ion in to water soluble phosphate compound.

CAS:Phosphoric acid is a colorless, corrosive liquid with an acrid odor. It is soluble in water and reacts with most organic substances. Phosphoric acid is used as a catalyst, in the manufacture of fertilizers and food additives, and as the active ingredient in some cola drinks. It also has applications in the textile industry, where it is used to remove starch from cotton fibers. Phosphoric acid is an oxidizing agent that can be used to disinfect cancer tissues. This chemical has high resistance to transfer reactions, which makes it useful for analytical methods such as electrochemical impedance spectroscopy (EIS). The EIS technique can be used to measure pH levels by measuring the impedance of a solution when a small voltage is applied across its surface. Benzalkonium chloride is added as a preservative or bactericide because phosphoric acid readily reacts with many other organic materials and may cause explosions if not diluted with water. Phosphoric acid also has significant cytotFormula:H3O4PPurezza:Min. 95%Colore e forma:Clear Colourless LiquidPeso molecolare:98 g/molRef: 3D-FP45387
