reaction of acids with metals

• metal + acid reacts to make salt + hydrogen
• the more reactive a metal is, the more rapid a reaction is.
• a metal below hydrogen in the reactivity series will not react with dilute acids.
• magnesium reaction with hydrochloric acid:

  hydrochloric acid + magnesium reacts to form magnesium chloride + hydrogen
• magnesium reaction with sulfuric acid:

  sulfuric acid + magnesium reacts to form magnesium sulfate + hydrogen
• magnesium reacts rapidly with acids.
• zinc reaction with hydrochloric acid:

  hydrochloric acid + zinc reacts to form zinc chloride + hydrogen
• zinc reaction with sulfuric acid:

  sulfuric acid + zinc reacts to from zinc sulfate + hydrogen
• iron reaction with hydrochloric acid:

  hydrochloric acid + iron reacts to form iron chloride + hydrogen
• iron reaction with sulfuric acid:

  sulfuric acid + iron reacts to form iron sulfate + hydrogen
• iron reacts fairly slowly with acids.
• in magnesium, zinc and iron reaction with a dilute acid, the acids always gain electrons and are therefore reduced.
• in magnesium, zinc and iron reacting with dilute acids, the metals always lose electrons and are therefore oxidised.
