Question
- A. Formation of salt and water
- B. Formation of carbon dioxide
- C. Formation of alcohol
- D. Formation of ester
Answer
The correct option is Formation of carbon dioxide.
Explanation
The correct option is Formation of carbon dioxide. Formation of carbon dioxide is correct because it directly supports the approved learning objective to describe what happens when any of the first four carboxylic acids react with carbonates. This belongs to Carboxylic acids within Reactions of alkenes and alcohols (chemistry only), so the answer must use the correct organic chemistry context. The other options are incorrect when they confuse the organic family, formula type, reaction condition, product, or property being tested. Keep molecular formula, structural formula, displayed formula, and general formula distinct. Do not confuse alkanes with alkenes, saturated with unsaturated, cracking with combustion, polymers with monomers, or hydrocarbons with oxygen-containing alcohols and carboxylic acids. When formulae are used, preserve the stored notation exactly and explain the GCSE chemistry idea in words rather than using unsupported displayed-formula diagrams.
Common mistake
Misunderstanding Carboxylic Acid Reactions
Students often think that carboxylic acids react with carbonates to produce only carbon dioxide and water.
Emphasize that the reaction also produces a salt, in addition to carbon dioxide and water, when carboxylic acids react with carbonates.
