Did you know?
WebAs per the Henderson-Hasselbalch equation, pH = pK a + log ( [CH 3 COO – ]/ [CH 3 COOH]) Here, K a = 1.8*10 -5 ⇒ pK a = -log (1.8*10 -5) = 4.7 (approx.). Substituting the values, we get: pH = 4.7 + log (0.6M /0.4M) = 4.7 + log (1.5) = 4.7 + 0.17 = 4.87 Therefore, the pH of the solution is 4.87.
