WebThe oxyacids of phosphorous are reducing agents. H 3P O3 is a good reducing agent than H 3P O4. The reducing nature of these acids is based on the no of hydrogen atoms bonded to the central metal atom. As more number of H attached to phosphorous more is its reducing nature. WebH3PO4 = H2PO4 (1-) + H+ pKa = 2.16 H2PO4 (1-) = HPO4 (2-) + H+ pKa = 7.21 HPO4 (2-) = PO4 (3-) + H+ pKa = 12.32 The smaller the pKa value the stronger the acid. All of the pKa values for sulfuric acid are less than those of phosphoric acid, hence sulfuric acid is the strongest acid. 3 Connor Foley I know a decent amount of chemistry.
