Web14 feb. 2012 · Phenolphthalein gives us carbonate and methyl orange gives us bicarbonate. Total alkalinity is calculated from carbonate and bicarbonate values. If you can estimate carbonate from pH go ahead, but you can have tremendous amounts of ions in solution at the same the pH. I hope this helps. Reply.
