Is there a reason why in the graph the pH goes rapidly at the start of reaching the 1st equilibrium then almost flats out half way there and then shoots up to the equilibrium? Same thing with the line to the 2nd equilibrium.
in a reaction like HCl+NaOH-> NaCl+H2O , HCl is monoprotic but what would happen to the result if it were diprotic? would it be HNaCl+H2O ? or NaCl + HOH2+?
