Equilibrium Question 738
Question: The following equilibrium is established when $ HCl{O^{}}_4 $ is dissolved in weak acid $ HF $ . $ HF+HClO_4\rightarrow ClO_4^{-}+H_2{F^{+}} $ Which of the following is correct set of conjugate acid
Options:
A) HF and $ HClO_4 $
B) HF and $ ClO_4^{-} $
C) HF and $ H_2{F^{+}} $
D) $ HClO_4 $ and $ H_2{F^{+}} $
Show Answer
Answer:
Correct Answer: C
Solution:
Conjugate acid base pair differ by a proton ( $ {H^{+}} $ ) $ \underset{(acid)}{\mathop{H_2{F^{+}}}},\xrightarrow{-{H^{+}}}\underset{(base)}{\mathop{HF}}, $
