CAS 7732-18-5

Acqua

Descrizione:

Acqua, con la formula chimica H₂O e numero CAS 7732-18-5, è una sostanza vitale e ubiqua sulla Terra. È una molecola polare, caratterizzata dalla sua forma piegata, che risulta in un momento dipolare significativo. Questa polarità contribuisce alle sue eccellenti proprietà di solvente, permettendole di sciogliere un'ampia gamma di sostanze ioniche e polari. Acqua ha un'alta capacità calorifica specifica, che le consente di assorbire e trattenere calore, svolgendo un ruolo cruciale nella regolazione delle temperature negli ambienti naturali. Mostra proprietà uniche come alta tensione superficiale e coesione, che sono essenziali per vari processi biologici. Acqua esiste in tre stati: solido (ghiaccio), liquido e gas (vapore di Acqua), con le sue transizioni di fase che avvengono a condizioni specifiche di temperatura e pressione. Inoltre, Acqua ha un alto calore latente di vaporizzazione, che è importante per processi come il raffreddamento e la regolazione del clima. La sua densità è massima a 4°C, il che porta il ghiaccio a galleggiare sul Acqua liquido, una caratteristica essenziale per gli ecosistemi acquatici. In generale, Acqua è fondamentale per la vita, influenzando reazioni chimiche, funzioni biologiche e sistemi ambientali.
