Vedclass · Answer

(D) For $HNO_3$ to act as a base,it must accept a proton $(H^+)$ from another substance.This occurs in the presence of a stronger acid,such as $H_2SO_4$ or $HClO_4$.Among the given options,$HIO_4$ (periodic acid) is the strongest acid because the iodine atom is in a high oxidation state $(+7)$ and is bonded to four highly electronegative oxygen atoms,which stabilizes the conjugate base $(IO_4^-)$ through resonance and inductive effects.Therefore,$HIO_4$ is the strongest acid among the choices provided.

In the reaction where $HNO_3$ acts as a base,which of the following acts as the strongest acid?
