Você acha que o sódio reage direto com o nitrato de cobalto? Não é isso que está acontecendo — e entender esse detalhe muda completamente a leitura do experimento. Quando o nitrato de cobalto entra na água, ele se dissocia: Co₂ → Co²⁺ + 2 NO₃⁻ Ou seja, o que realmente existe na solução são íons livres, principalmente Co²⁺. Ao adicionar sódio metálico, ele não reage com o nitrato nem com o cobalto primeiro. Ele reage violentamente com a água: 2 Na + 2 H₂O → 2 NaOH +
