Determination of potassium hydrogen carbonate into potassium carbonate. During a titration, the volume of one reagent, the analyte, is predetermined while the other reagent, the titrant, is prepared in a buret and slowly introduced to the analyte solution. 6. 5. These uncertainties may have been brought about by the apparatus used. 3. The titration curve contains three regions with nearly flat gradually increasing slopes; the first two are called buffer regions, where the acid in the solution rapidly consumes the base—the titrand. The buret contains a large air bubble in the tip, which disappears in the course of the titration. The experiment cannot be stopped at the equivalence point as there are no materials to do that. ...read more.
