CAS 7440-23-5
:Sodio
Descrizione:
Sodio, con il numero CAS 7440-23-5, è un metallo alcalino altamente reattivo appartenente al Gruppo 1 della tavola periodica. È caratterizzato dal suo aspetto morbido e bianco argenteo ed è noto per la sua bassa densità, essendo meno denso dell'acqua. Sodio ha un punto di fusione di circa 98 gradi Celsius e un punto di ebollizione di circa 883 gradi Celsius. Perde facilmente un elettrone per formare un catione (Na+), il che lo rende altamente reattivo, in particolare con l'acqua, producendo idrossido di Sodio e gas idrogeno. Questa reattività richiede che Sodio venga conservato sotto olio o in un'atmosfera inerte per evitare che reagisca con l'umidità nell'aria. Sodio gioca un ruolo cruciale nei sistemi biologici, in particolare nella funzione nervosa e nell'equilibrio dei fluidi. È anche un componente essenziale in varie applicazioni industriali, inclusa la produzione di vetro, saponi e come scambiatore di calore nei reattori nucleari. A causa della sua reattività, Sodio deve essere maneggiato con cura e devono essere adottate misure di sicurezza appropriate quando si lavora con questo elemento.
