CAS 7732-18-5: Agua

Descripción: Agua, con la fórmula química H₂O y el número CAS 7732-18-5, es una sustancia vital y ubicua en la Tierra. Es una molécula polar, caracterizada por su forma doblada, lo que resulta en un momento dipolar significativo. Esta polaridad contribuye a sus excelentes propiedades como disolvente, permitiéndole disolver una amplia gama de sustancias iónicas y polares. Agua tiene una alta capacidad calorífica específica, lo que le permite absorber y retener calor, desempeñando un papel crucial en la regulación de temperaturas en entornos naturales. Exhibe propiedades únicas como alta tensión superficial y cohesión, que son esenciales para varios procesos biológicos. Agua existe en tres estados: sólido (hielo), líquido y gas (vapor de Agua), con sus transiciones de fase ocurriendo a condiciones específicas de temperatura y presión. Además, Agua tiene un alto calor latente de vaporización, que es importante para procesos como la refrigeración y la regulación del clima. Su densidad es más alta a 4°C, lo que lleva a que el hielo flote sobre el Agua líquido, una característica esencial para los ecosistemas acuáticos. En general, Agua es fundamental para la vida, influyendo en reacciones químicas, funciones biológicas y sistemas ambientales.
