Acids…

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

5. Word equations Write these into word equations: • Magnesium and hydrochloric acid • Hydrochloric acid and sodium carbonate • Sulfuric acid and zinc carbonate • Zinc and nitric acid • Copper and sulfuric acid • Nitric acid and calcium carbonate

6. Word equations • Magnesium and hydrochloric acid magnesium chloride+hydrogen . 2. Hydrochloric acid and sodium carbonate Sodium chloride + carbon dioxide +water. • Sulfuric acid and zinc carbonate Zinc sulfate + carbon dioxide+water 4. Zinc and nitric acid Zinc nitrate+hydrogen • Copper and sulfuric acid copper sulfate +water • Nitric acid and calcium carbonate Calcium nitrate + carbon dioxide+water
