Answer on Question #44399 – Chemistry – Other −) Question is amphiprotic. Write another equation showing how it acts The hydrogen oxalate ion (HC2O4 as a base toward water. Express your answer as a chemical equation. Identify all of the phases in your answer. Answer According to the Brønsted–Lowry theory, an acid is a species able to lose, or "donate" a proton (H+) while a base is a species with the ability to gain, or "accept," a proton. The hydrogen oxalate ion can gain a proton acting as a base towards water, while the latter donates proton acting as an acid: HC2O4− + HOH → HC2O4H base acid + OH– conjugated acid conjugated base www.AssignmentExpert.com
