What is the percent dissociation of acetic acid if the solution has a pH = 4.74 and a pK_a = 4.74? A)100% B)50% C)10% D)1%

Question

Quizplus · Accepted Answer

The percent dissociation of acetic acid in this case is 50% because when the pH of the solution equals the pKa of the acid, the concentrations of the acid and its conjugate base are equal, indicating that 50% of the acid has dissociated into its conjugate base.
