CAS 7732-18-5: Wasser
Beschreibung:
Wasser, mit der chemischen Formel H₂O und der CAS-Nummer 7732-18-5, ist eine lebenswichtige und allgegenwärtige Substanz auf der Erde. Es ist ein polares Molekül, das durch seine gebogene Form gekennzeichnet ist, was zu einem signifikanten Dipolmoment führt. Diese Polarität trägt zu seinen hervorragenden Lösungseigenschaften bei, die es ihm ermöglichen, eine breite Palette von ionischen und polaren Substanzen zu lösen. Wasser hat eine hohe spezifische Wärmekapazität, die es ihm ermöglicht, Wärme zu absorbieren und zu speichern, was eine entscheidende Rolle bei der Regulierung der Temperaturen in natürlichen Umgebungen spielt. Es zeigt einzigartige Eigenschaften wie hohe Oberflächenspannung und Kohäsion, die für verschiedene biologische Prozesse unerlässlich sind. Wasser existiert in drei Zuständen: fest (Eis), flüssig und gasförmig (Dampf von Wasser), wobei seine Phasenübergänge unter spezifischen Temperatur- und Druckbedingungen stattfinden. Darüber hinaus hat Wasser eine hohe latente Wärme der Verdampfung, die für Prozesse wie Kühlung und Klimaregulierung wichtig ist. Seine Dichte ist bei 4°C am höchsten, was dazu führt, dass Eis auf flüssigem Wasser schwimmt, eine wesentliche Eigenschaft für aquatische Ökosysteme. Insgesamt ist Wasser grundlegend für das Leben und beeinflusst chemische Reaktionen, biologische Funktionen und Umweltsysteme.
