思路分析
Context: When applying the Henderson-Hasselbalch equation to the alpha-amino group, [A-] denotes the conjugate base form of the group, i.e., the deprotonated species. Option 1: 'The concentration of protons in the solution.' This would correspond to [H+], not [A-]; it......Login to view full explanation
