CAS 7732-18-5: Água

Descrição: Água, com a fórmula química H₂O e número CAS 7732-18-5, é uma substância vital e ubíqua na Terra. É uma molécula polar, caracterizada por sua forma dobrada, o que resulta em um momento dipolar significativo. Essa polaridade contribui para suas excelentes propriedades como solvente, permitindo que dissolva uma ampla gama de substâncias iônicas e polares. Água possui uma alta capacidade calorífica específica, o que lhe permite absorver e reter calor, desempenhando um papel crucial na regulação das temperaturas em ambientes naturais. Apresenta propriedades únicas, como alta tensão superficial e coesão, que são essenciais para vários processos biológicos. Água existe em três estados: sólido (gelo), líquido e gás (vapor de Água), com suas transições de fase ocorrendo em condições específicas de temperatura e pressão. Além disso, Água tem um alto calor latente de vaporização, que é importante para processos como resfriamento e regulação climática. Sua densidade é máxima a 4°C, o que faz com que o gelo flutue sobre o Água líquido, uma característica essencial para os ecossistemas aquáticos. No geral, Água é fundamental para a vida, influenciando reações químicas, funções biológicas e sistemas ambientais.
