Carboxylic Acids — Interactive Lesson (Ages 14–16)

The sour taste of vinegar, the sting of an ant and the zing of citrus all come from carboxylic acids. This 21-slide interactive lesson on carboxylic acids takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Carboxylic Acids in GCSE Chemistry

Pupils identify the –COOH group, name methanoic to butanoic acid by counting every carbon, and explain why they are weak acids that only partially ionise. They predict the products of reactions with carbonates, metals and alcohols, name salts such as magnesium ethanoate, and explain why baking soda soothes an ant sting.

What Pupils Will Learn

• Identify the –COOH functional group.
• Name the first four members of the series and write their formulae.
• Describe how they react with carbonates and metals.
• Explain why they are weak acids.
• State some everyday uses of carboxylic acids.
