Carboxylic acids are a homologous series of           compounds that contain the -COOH functional group.

Weak acids partially dissociate to form Hᐩ ions in solution.

A carbonate is a compound containing the CO₃²ᐨ ion. An example is calcium carbonate CaCO₃.

Esters are a homologous series of compounds that contain the -COO- functional group.

Ethyl ethanoate is an ester produced from the alcohol ethanol and the carboxylic acid ethanoic acid.
