Two aliquot of a water sample is titrated against a strong acid using phenolphthalein and bromocresol green indicator. The volume for the phenolphthalein endpoint and for the bromocresol green endpoint are equal, what is/are the probable source of alkalinity? a) Hydroxide b) Bicarbonate c) Carbonate d) Both Hydroxide and Carbonate In addition, what would be the probable source of alkalinity if the volume for bromocresol green endpoint is 13.5mL and there was no phenolphthalein endpoint?
