Chemistry

• acid + metal = salt + hydrogen
• hydrochloric acid has the term chloride and sulphuric acid has the term sulphate
• bases are chemicals that neutralise acids and produce a salt and a water
• Acids: Hydrochloric acid, sulfuric acid, nitric acid
• 3 bases: copper oxide, iron (III) hydroxide, sodium hydroxide
• Metal carbonates: sodium carbonate, potassium carbonate and calcium carbonate
• acid + metal carbonate = salt + water + carbon dioxide
• weak acids are reversible reactions: carbonic acid, ethnic acid and citric acid
