  • Alkalinity Lab

    The four methods used for quantification of alkalinity (4) are summarized below: •Use of a pH indicator: a change in the color from pure yellow to orange is observed and recorded when a known pH is reached. In this his experiment we used methyl orange as indicator The consumed volume until specific pH allow us to know how much volume is required to reach the endpoint. •Visual identification from titration curve; the data are recorded…
