WebThe concentration of carbonic acid, H 2 CO 3 is approximately 0.0012 M, and the concentration of the hydrogen carbonate ion, HCO 3 −, is around 0.024 M. Using the Henderson-Hasselbalch equation and the p Ka of carbonic acid at body temperature, we can calculate the pH of blood: pH = p K a + log [ base] [ acid] = 6.4 + log 0.024 0.0012 = 7.7 WebApr 30, 2024 · [H+] = x = 0.003; pH = 2.5 The combination of the weak acid (CH3COOH) and its conjugate base (CH3COO-) is buffer. Use the Henderson-Hasselbalch equation: pH = pKa + log [CH3COO-]/ [CH3COOH] [CH3COO-] (from CH3COONa) is 0.01*1.0/0.02 = 0.50 M and the same for [CH3COOH]. This makes the log term = 0 and pH = pKa = 4.7 PLEASE HELP!!!
