Salts and esters of carboxylic acids and related compounds are named by
placing the name of the metal or the esterifying group in front of the name
of the acid anion, separated by a space. Joint occurrence of both functions
is indicated accordingly. Acid salts and esters are named analogously.
Complex cases can also be named more descriptively: ... salt or ... ester of
... acid. (Similar provisions are valid for other acid derivatives such as amides and nitriles.)
