1 Metals Revision Properties and Reactions of Metals

2

3 Properties of Metals Usually Solids Tough Shiny Conduct Electricity Conduct Heat

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

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

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

7 REACTION RULE Acid + Metal Oxide  Salt + Water

8 Equations Copper Oxide + Sulphuric Acid  Copper Sulphate + Water CuO + H 2 SO 4  CuSO 4 + H 2 O

9 Reaction Rule Acid + Alkali  Salt + Water

10 Reaction Equations Potassium + Hydrochloric  Potassium + Water Hydroxide Acid Chloride KOH + HCl  KCl + H 2 O

11 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

12 pH of Less than 7 = Acid pH of Over 7 = Alkali pH = 7 = Neutral

13 What do these Safety symbols stand for?

14 Try Writing Formula Equations Magnesium + Oxygen  Magnesium Oxide

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

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