Question

Why can the relative strength of HCl and HClO$_4$ be determined in acetic acid but not in water?

• A. Because acetic acid is a weaker acid than H$_3$O$^+$
• B. Because acetic acid is a stronger acid than H$_3$O$^+$
• C. Because acetic acid is a weaker Bronsted-Lowry base than H$_2$O
• D. Because acetic acid is a stronger Bronsted-Lowry base than H$_2$O

Hint:

The relative strength of acids can be measured in solvents with weaker acids, such as acetic acid.

Answer 1

The Correct Option is A

Acetic acid is a weaker acid than water, so in acetic acid, it is easier to distinguish between the strengths of HCl and HClO$_4$ based on their ability to donate protons.
