  1. Metals Revision Properties and Reactions of Metals

  2. Properties of Metals • Usually Solids • Tough • Shiny • Conduct Electricity • Conduct Heat

  3. Properties of Non Metals • The Opposite! • Solids, Liquids and Gases • Weak and Brittle • Dull • Do Not conduct electricity or heat

  4. Reactions of Metals with Acid METAL + ACID  SALT + HYDROGEN Test for Hydrogen? Burns with a squeaky pop!

  5. Acid and Carbonate Rule Acid + Carbonate  Salt + Water + Carbon Dioxide Test For Carbon Dioxide? Turns limewater milky

  6. REACTION RULE Acid + Metal Oxide  Salt + Water

  7. Equations Copper Oxide + Sulphuric Acid  Copper Sulphate + Water CuO + H2SO4  CuSO4 + H2O

  8. Reaction Rule Acid + Alkali  Salt + Water

  9. Reaction Equations Potassium + Hydrochloric  Potassium + Water Hydroxide Acid Chloride KOH+ HCl  KCl + H2O

  10. pH Scale • Using indicator will tell you the pH of the substance you are investigating • Match the colour to the chart • pH of Less than 7 = Acid • pH of Over 7 = Alkali • pH = 7 = Neutral

  11. pH of Less than 7 = AcidpH of Over 7 = AlkalipH = 7 = Neutral

  12. What do these Safety symbols stand for?

  13. Try Writing Formula Equations Magnesium + Oxygen  Magnesium Oxide

  14. Try Writing Formula Equations Sodium + Hydrochloric  Sodium + Water Hydroxide Acid Chloride

  15. Try Writing Formula Equations Sulphuric + Copper  Copper + Water + Carbon Acid Carbonate Sulphate Dioxide
