What do carboxylic acids form when they react with metal carbonates?

Carboxylic acids react with metal carbonates to produce a salt, carbon dioxide, and water through an acid-base reaction. During this process, the carboxylic acid donates a proton (H+) to the carbonate, resulting in the formation of a metal salt from the acid and carbonate. The carbonate then decomposes, releasing carbon dioxide gas, which can be observed as fizzing or bubbling during the reaction. Additionally, water is produced as a byproduct. This reaction is quite typical in organic chemistry when studying acid-base interactions and is fundamental to understanding how different chemical groups behave in reactions.

The other options describe different reactions or products that do not accurately represent the products of a carboxylic acid reacting with metal carbonates.
