1. The problem statement, all variables and given/known data 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 2. Relevant equations None that I know of. 3. 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.
