what is the conjugate acid of the monohydrogen phosphate ion, h₂po₄⁻?

what is the conjugate acid of the monohydrogen phosphate ion, h₂po₄⁻?
Answer
Explanation:
Step1: Recall conjugate - acid concept
A conjugate acid is formed when a base accepts a proton ($H^+$).
Step2: Add a proton to the given ion
When $H_2PO_4^-$ accepts a proton ($H^+$), the reaction is $H_2PO_4^-+H^+\rightarrow H_3PO_4$.
Answer:
$H_3PO_4$
