Again, this type of titration has the 4 stages: Acid before any base is added. Base added but acid in excess. Equivalence (Stoichiometric) Point. Base in excess When the acid in the beaker is WEAK, stages 1-3 are different than in a SA-SB titration. Stage 1 – Only the Acid is present, but it is a WEAK acid, so the [H3O+] is NOT equal to [acid]

In other words a base excess of ‘MINUS 6′ means we would have to ADD 6mmol of bicarbonate to get to a pH of 7.4. Practically speaking the base excess (or base deficit) tells us whether there is a metabolic problem (regardless of the CO2 level that determines respiratory acidosis and alkalosis) The Henderson-Hasselbalch Equation

moles excess base = 2.70x10-2 moles - 2.50x10-2 moles = 2.0x10-3 moles NaOH. M OH- = M NaOH = 8.7x10-3 M OH-pOH = -log 8.7x10-3 = 2.06 pH = 14 – 2.06 = 11.94 *Excess NaOH remains - this is the primary source of OH-. We can neglect the hydrolysis of the conjugate base because this would contribute a relatively small amount of OH- compared to ...
