1. Acids… Learning objectives: Know that salts are formed from reactions with acids. Know how to write correct word equations. Know what salts are formed from certain acids. Turn to page 64

2. Acids and Alkalis When an acid neutralises an alkali two chemicals are made: Salt Water Sulfuric acid + sodium hydroxide sodium sulfate + water Acid Alkali salt Nitric acid + potassium hydroxide potassium nitrate + water Acid Alkali salt

3. Salts The name of the salt comes from the name of the acid: Hydrochloric acid makes chloride salts Sulfuric acid makes sulfate salts Nitric acid makes nitrate salts.

4. Word Equations Acid + alkali salt + water Give an example Acid + carbonate salt + carbon dioxide + water Give an example Acid + metal salt + hydrogen Give an example
