You have two buffered solutions.Buffered solution 1 consists of 5.0 M HOAc and 5.0 M NaOAc;buffered solution 2 is made of 0.050 M HOAc and 0.050 M NaOAc.
-How do the pHs of the buffered solutions compare?

Question

Quizplus · Accepted Answer

The pH of a buffered solution is determined by the Henderson-Hasselbalch equation, which depends only on the ratio of the concentrations of the weak acid and its conjugate base, and the acid dissociation constant (Ka) of the weak acid. Since both buffered solutions have the same ratio of HOAc to NaOAc and the same weak acid (HOAc), the pH will be the same for both solutions. The Ka values are not necessary to determine the pH comparison between the two solutions.
