Question

$HCl$ behaves as......in the reaction: $HCl+HF\to H_2^{+}Cl+F^{-}$

• A. weak base
• B. weak acid
• C. strong base
• D. strong acid

Answer 1

Answer: (A)

In the reaction, $HCl+HF\to H_2^{+}Cl+F^{-}$ $HCl$ is taking up a proton, hence it is acting as a base. Its conjugate acid $(H_2^{+}Cl)$ has a strong tendency to loose proton, hence it is a strong acid, and therefore, its conjugate base (HC1) will be a weaker base.
