Chuva ácida não é apenas consequência de poluição industrial. Ela é um processo natural da atmosfera. Toda água da chuva já é levemente ácida porque o dióxido de carbono , liberado pela respiração de plantas, animais e pela decomposição da matéria orgânica, dissolve-se na água das nuvens formando ácido carbônico: CO₂ + H₂O ⇌ H₂CO₃ Esse equilíbrio faz com que a chuva “natural” tenha pH em torno de 5,6. Portanto, certa acidez é normal e faz parte dos ciclos biogeoquímicos do plane
