Metals Revision Properties and Reactions of Metals
Properties of Metals • Usually Solids • Tough • Shiny • Conduct Electricity • Conduct Heat
Properties of Non Metals • The Opposite! • Solids, Liquids and Gases • Weak and Brittle • Dull • Do Not conduct electricity or heat
Reactions of Metals with Acid METAL + ACID SALT + HYDROGEN Test for Hydrogen? Burns with a squeaky pop!
Acid and Carbonate Rule Acid + Carbonate Salt + Water + Carbon Dioxide Test For Carbon Dioxide? Turns limewater milky
REACTION RULE Acid + Metal Oxide Salt + Water
Equations Copper Oxide + Sulphuric Acid Copper Sulphate + Water CuO + H2SO4 CuSO4 + H2O
Reaction Rule Acid + Alkali Salt + Water
Reaction Equations Potassium + Hydrochloric Potassium + Water Hydroxide Acid Chloride KOH+ HCl KCl + H2O
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
pH of Less than 7 = AcidpH of Over 7 = AlkalipH = 7 = Neutral
