🎯 Exam Focus: Carboxylic Acids

very-high Identification test (2 marks): Describe the carbonate test — state reagent (sodium carbonate), observation (fizzing), gas test (limewater goes milky), conclusion (carboxylic acid identified).

high Weak acid explanation (2 marks): Must say "partially dissociates" and use ⇌ symbol in any dissociation equation.

high Naming and formula (1-2 marks): Use "-anoic acid" ending; general formula CₙH₂ₙ₊₁COOH.

medium Ester formation (2 marks): Carboxylic acid + alcohol → ester + water (uses ⇌ — it's reversible).

Edexcel 1CH0: Examined in Paper 2 (1CH0/2). Reactions of carboxylic acids with alcohols (esterification) and with carbonates are tested in Edexcel Paper 2. In Edexcel-style questions, the command word "Suggest" appears frequently — use your chemistry knowledge to apply to an unfamiliar context.
