Question

\[\ce{H2PO^-_4}\] the conjugate base of ____________.

विकल्प

• \[\ce{PO^{3-}_4}\]

• P₂O₅

• H₃PO₄

• \[\ce{HPO^{2-}_4}\]

Answer 1

\[\ce{H2PO^-_4}\] the conjugate base of H₃PO₄.

Explanation:

\[\ce{\underset{acid 1}{H3PO4} + \underset{base 1}{H - OH} ⇌ \underset{acid 2}{H3O^+} + \underset{base}{H2PO^-_4}}\]

∴ \[\ce{H2PO^-_4}\] is the conjugate base of H₃PO₄
