Part C What is the conjugate acid of HPO42- ? Express your answer as a chemical formula. View Available Hint(s) Submit Previous Answers Request Answer According to the Brønsted-Lowry theory, an acid is any substance (molecule or ion) that can transfer a proton (H" ion) to another substance, and a base is any substance that can accept a proton. Acid-base reactions are proton-transfer reactions, as follows: + HA + acid B base = BH acid A. base Chemical species whose...
