Current Question (ID: 8551)

Question:

$\text{The addition of } \text{HCl does not suppress the ionization of:}$

Options:

1. $\text{Acetic acid}$
2. $\text{Benzoic acid}$
3. $\text{H}_2\text{S}$
4. $\text{H}_2\text{SO}_4$

Solution:

\text{Hint: Use concept of common ion effect} \text{The common ion effect only works for weak electrolytes. For example, acetic acid is a weak electrolyte so when HCl is added to acetic acid solution, the ionization of acetic acid is suppressed because of common ion effect of } \text{H}^{+}. \text{But } \text{H}_2\text{SO}_4 \text{ is a strong electrolyte and it fully dissociates into } 2\text{H}^{+} \text{ and } \text{SO}_4^{2-}. \text{Thus, addition of HCl does not affect the ionization of } \text{H}_2\text{SO}_4.
