$H_2PO_4^{-}, PO_4^{3-}$

Vedclass · Answer

(D) conjugate acid-base pair differs by only one proton $(H^+)$. $(a)$ $HPO_3^{2-}$ and $PO_3^{3-}$ differ by one $H^+$, so they form a conjugate pair. $(b)$ $H_2PO_4^{-}$ and $HPO_4^{2-}$ differ by one $H^+$, so they form a conjugate pair. $(c)$ $H_3PO_4$ and $H_2PO_4^{-}$ differ by one $H^+$, so they form a conjugate pair. $(d)$ $H_2PO_4^{-}$ and $PO_4^{3-}$ differ by two protons $(2H^+)$, therefore they do not form a conjugate acid-base pair.

$A$. $HI$	$(i)$ $3.2 \times 10^9$
$B$. $HF$	$(ii)$ $3.5 \times 10^{-4}$
$C$. $HCl$	$(iii)$ $1.3 \times 10^6$
$D$. $HBr$	$(iv)$ $1.0 \times 10^9$
