Zinc reacting with a weak acid. The reaction is very slow,shown by the few small bubbles of hydrogen gas being generated. This is because metallic zinc in air reacts with atmospheric carbon dioxide to form a passivating layer of zinc carbonate which is resistant to weak acids. The reaction of zinc in acid is given by the equation Zn (s) + 2H+ (aq) = Zn2+ (aq) + H2 (g) | |
