Uhm, well he's totally misunderstood the task anyway. It's NOT about pH, it's about ALKALINITY which is DIFFERENT from pH. Alkalinity is a measurement of water's capacity to RESIST CHANGE IN pH, i.e. the buffer system I wrote has carbonate ions (or whatever) converting the acid to CO2 and water until we're all out of carbonate ions, so...
THANKS ANYWAY
