Os médicos costumam prescrever às pessoas
hipertensas uma dieta com baixo teor de sódio. Entretanto,
esse elemento a que os médicos se referem não é o sódio
metálico, um metal muito reativo que, em contato com a
água, libera grande quantidade de energia. Na verdade,
essa recomendação refere-se aos íons sódio (Na+
), que são
ingeridos quando consumimos, principalmente, alimentos
que contenham o sal de cozinha. Da mesma maneira,
quando os médicos prescrevem ferro às pessoas anêmicas,
não quer dizer que elas devam “comer pregos” ou outro
objeto feito de ferro. O que se indica é a ingestão de íons
de ferro (II), presente, por exemplo, em FeSO4
