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 + WaterHydroxide 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 = Alkali

pH = 7 = Neutral
