Webb8 nov. 2024 · Calculate the pH of the buffer solution. According to the Henderson Hasselbalch equation, pH = pKa + log ( [CH 3 COO–]/ [CH 3 COOH]) Ka = 1.8 10 -5 ⇒ pKa= -log (1.8 10 -5) = 4.7 On substituting the values in the equation, we have: pH = 4.7 + log (0.6M /0.4M) = 4.7 + log (1.5) = 4.7 + 0.17 = 4.87 Thus, the pH of the solution is 4.87.
