How do metals react with dilute acids? Explain with the help of an example.
Metals react with dilute acids to form metallic salts and hydrogen gas. For example, Aluminium foil reacts with dilute hydrochloric acid to produce aluminum chloride and hydrogen gas.
The balanced chemical equation for the reaction is:
2Al(s) + 6HCl(aq) 2AlCl3(aq) + 3H2(g).
