Updated Mathematica to explore what equilibrium the textbook value of pK=6.1 gives compared to using the initial values read off Peter's slides. Change pK = pKbyInitial to pK = pKfromTextbook to see the difference: textbook value does not match initial conditions on slide being at equilibrium, and ODE runs to a pH of around 4.5!
