Question

Given the list of pKa values (see attachment), which acid will have the largest amount of conjugate base present in the solution at equilibrium?

Answer 1

pKa is the -log of the dissociation constant, so the lower the value the higher the extent of dissociation. The conjugate base is present when the acid dissociates.

\(\sf HA\rightarrow H^++A^-\) where \(A^-\) is the conjugate base.

With this information, what do you think the answer is?

Answer 2

HCl, correct?
