Explanation:

Oxyanions are polyatomic ions that contain oxygen. For an acid like \(H_2CO_3\) (carbonic acid), when it donates protons (\(H^+\)), the remaining part is the oxyanion. The general formula for the dissociation of \(H_2CO_3\) is \(H_2CO_3
ightarrow 2H^++CO_3^{2 -}\). The \(CO_3^{2 -}\) ion is named based on the acid - anion naming convention. Since the acid is carbonic acid, the oxyanion is carbonate.

Answer:

carbonate
