Metals and acids

• Metals that react with water


  • They react very quickly with acids
• Metals that don't react with water


  • They do react with acids
• When metals react with acids

  1. They produce hydrogen

  2. They produce a salt
• metal + acid- salt + hydrogen
• Salts formed from acids


  • Chlorides (from hydrochloric acid)
  • Sulfates (from sulfuric acid)
  • Nitrates (from nitric acid)
• Magnesium reacting with sulfuric acid


  • Magnesium + sulfuric acid → magnesium sulfate + hydrogen
• Magnesium + sulfuric acid


  • Mg + H2SO4 → MgSO4 + H2
