According to the following pKa values listed for a set of acids, which would lead to the strongest conjugate base?
A) -2
B) 1
C) 7
D) 25
E) 50

Question

Quizplus · Accepted Answer

The strength of a conjugate base is inversely related to the strength of its corresponding acid. A higher pKa value indicates a weaker acid, thus leading to a stronger conjugate base. Therefore, with a pKa of 50, the corresponding conjugate base would be the strongest among the options given.
