WebAug 30, 2024 · The C O 2 forms carbonic acid ( H 2 C O 3) when dissolved in water that then acts as a buffer, reducing the accuracy of data. After boiling water, most of the C O 2 will be removed from the solution allowing the solution to be titrated to a more accurate endpoint. The endpoint is the point where all of the analyte has be reacted with the reagent.
