Por que uma mistura de sulfato de cobre, ácido clorídrico e papel-alumínio consegue produzir um gás inflamável? O principal gás liberado é o hidrogênio, H₂. E o mais interessante é que o sulfato de cobre tem um papel importante para fazer a reação avançar rapidamente. Quando o alumínio entra na solução, os íons Cu²⁺ podem ser reduzidos a cobre metálico sobre sua superfície, enquanto o alumínio é oxidado. Esse depósito de cobre cria regiões de contato entre metais diferentes e favorece processo
