SOLVED: Question 6. What are the concentrations of Acetic Acid (HA) and sodium acetate (Na' and A ) in a 0.2 M acetate buffer at pH 5 (Ka =1.85x10 5) Solution Henderson-Hasselbalch equation pH = pKa Log [Salt]/ [Acid] Thus, 5 =4.733 Log [Salt]/ [Acid] and 5 4.733 = Log[Salt]/ [Acid] = 0.267 Thus, ratio of [Salt]/[Acid] = 1.85
