Question
Write the balanced equation for the reaction of butanoic acid with sodium carbonate.
Answer
The balanced equation is: C4H8O2 + Na2CO3 → 2 C4H7O2Na + H2O + CO2.
Explanation
This question assesses the student's ability to write balanced chemical equations for reactions involving carboxylic acids. It requires knowledge of the reactants and products, as well as the ability to balance the equation correctly. This response is aligned to Carboxylic acids because it explains describe what happens when any of the first four carboxylic acids react with carbonates using the correct AQA GCSE Chemistry organic context. 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.
