H4PO4<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>A conjugate acid is formed when a base accepts a proton (H\u207a). In the case of phosphate species, they exhibit different protonation states depending on the pH of the solution. To identify the conjugate acid of a given species, we must understand how these species can accept protons.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>H\u2082PO\u2084\u207b (dihydrogen phosphate)<\/strong>: This is the species in the middle of the phosphate ion&#8217;s dissociation. If H\u2082PO\u2084\u207b accepts a proton (H\u207a), it forms H\u2083PO\u2084 (phosphoric acid). This makes H\u2082PO\u2084\u207b the conjugate base of H\u2083PO\u2084. It is not the conjugate acid.<\/li>\n\n\n\n<li><strong>H\u2084PO\u2084 (tetrahydrogen phosphate)<\/strong>: When a phosphate ion accepts a proton (H\u207a), the resulting species is H\u2084PO\u2084. This is the correct conjugate acid for the phosphate base species. The protonation of H\u2083PO\u2084 results in H\u2084PO\u2084, which is a less common form of phosphate but still a conjugate acid.<\/li>\n\n\n\n<li><strong>H\u2083PO\u2084 (phosphoric acid)<\/strong>: This is already an acid, not a base. It can lose protons, but it cannot accept one to form a conjugate acid. It is a weak acid that dissociates to form H\u2082PO\u2084\u207b.<\/li>\n\n\n\n<li><strong>HPO\u2084\u00b2\u207b (hydrogen phosphate)<\/strong>: This is the conjugate base of H\u2082PO\u2084\u207b. If it accepts a proton, it forms H\u2082PO\u2084\u207b, not H\u2084PO\u2084.<\/li>\n\n\n\n<li><strong>OH\u207b (hydroxide)<\/strong>: Hydroxide is a strong base, not related to phosphate ions. If OH\u207b accepts a proton, it forms H\u2082O (water), but it is not connected to phosphate species in this context.<\/li>\n<\/ol>\n\n\n\n<p>Thus, <strong>H\u2084PO\u2084<\/strong> is the conjugate acid of H\u2083PO\u2084, and it is formed when H\u2083PO\u2084 accepts a proton.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The conjugate acid of is a.
