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. WebUse the Henderson-Hasselbalch equation to calculate the pH of a buffer solution that is 0.28 M in formic acid (HCO2H) and 0.55 M in sodium formate (HCO2Na). This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.
