Homework Statement
This is a problem taken from an old exam:
C. Which set of pKa’s is correct?
1. CH3COCH3 -7.0 2. CH3COCH3 -19.0
CH3COOH 4.8 CH3COOH -4.8
HCl 19.0 HCl 7.0
3. CH3COCH3 4.8 4. CH3COCH3 19.0
CH3COOH 7.0 CH3COOH 4.8
HCl 16.0 HCl -7.0
Homework Equations
None that I know of.
The Attempt at a Solution
I know from looking at the pKa values we were given in the lecture than the right answer is #4. Nevertheless, I was wondering if there was a way to get to this answer without learning the pKas by heart (a reasoning that would make the question logical).
Thank you,
Joanna.
