Answer
The "Acid A" has the weaker conjugate base. This is because, as we determined in (38a), "Acid A" is the stronger acid, and the strength of the acid is inversely proportional to the strength of its conjugate base.
Work Step by Step
- The strength of an acid is inversely proportional to the strength of its conjugate base.
Therefore, stronger acids have weaker conjugate bases, and weaker acids have stronger conjugate bases.
Since "Acid A" is the stronger acid of the pair, it will have the weaker conjugate base.
