WebSep 9, 2024 · pH = -log (4.2 x 10 -7 )+ log (0.035/0.0035) pH = 6.38 + 1 = 7.38. Therefore, the pH of the buffer solution is 7.38. This answer is the same one we got using the acid dissociation constant expression. Here we have used the Henderson-Hasselbalch to calculate the pH of buffer solution. WebHomework help starts here!
