(11) Titrate the KHP sample by adding NaOH untilthe end-point is reached. The titration is conducted by swirling the solution in the flask with your dominant hand while manipulating the stopcock with your other hand. As base is added you will observe a pink color caused by localized high base concentration. As you near the end-point, the color flashes throughout the solution, remaining for a longer time. When this occurs, add the base drop by drop until the end-point is reaches, as indicated by the first drop of base which causes a faint pink color to remain in the entire solution for at least 30 seconds. Record the final buret reading in your data table. (12) Refill the buret, if necessary. (13) Repeat steps 10-12 for flasks #2 and #3. (14) Upon completion of your titrations, place all solutions into the appropriate waste container.
