Reactions of Metals

• compounds definition 


  A new substance made up of two or more different chemicals that cannot be separated again
• magnesium sulphate 


  A compound that is made up of two substances- magnesium, sulphur, and oxygen
• copper carbonate 


  A compound that is made up of two substances- copper, carbon, and oxygen
• ion definition


  When compounds split up into particles- these are electrically charged
• acid


  A substance with a hydrogen ion that can have dangerous reactions
• alkali


  A substance with a hydroxide ion that can have dangerous reactions
• neutralisation 


  mixing an acid with an alkali- their ions come together and produce a new substance that is not dangerous
• salt


  when water is evaporated from some acid and alkali solutions, ions are left behind, they sit close together and become salt crystals
