Review the verified answer and explanation for this ETEA Educational Testing and Evaluation Agency past-paper question on CampusFin.

Calcium propionate and calcium acetate on heating together produce ______? Answer: Ethyl methyl ketone

When calcium salts of two different carboxylic acids (like calcium propionate and calcium acetate) are heated together, they undergo a ketonic decarboxylation reaction. This produces a mixed ketone, where one alkyl group comes from each acid, along with the release of carbon dioxide (CO₂) and calcium carbonate (CaCO₃).
