Metal + Non-oxidizing Acid Reactions
- Non-oxidizing acids include dilute hydrochloric acid (HCl(aq)) and dilute sulfuric acid (H2SO4(aq)).
- The ease with which a metal reacts is known as its activity.
A more active metal will react more readily with an acid than a less active metal.
Silver, gold and platinum are not active metals. They are known as noble metals# (or as inactive metals).
- All metals which are more active than lead react with dilute hydrochloric acid or dilute sulfuric acid##.
- Metals that react with these acids produce a metal salt and hydrogen gas:
metal + non-oxidizing acid → metal salt + hydrogen gas metal + dilute hydrochloric acid → metal chloride + hydrogen gas metal + dilute sulfuric acid → metal sulfate + hydrogen gas
Heat is also produced during these reactions.###
A more active metal will produce heat energy faster than a less active metal.
