The Titration Fill a buret to the 0 00 mL mark with the

The Titration Fill a buret to the 0 00 mL mark with the Standard 0 100 M KHP solution Fill a second buret to the 0 00 mL mark with the unknown sodium hydroxide solution Using the buret add about 10 00 mL of the acid KHP solution to an Erlenmeyer flask Add two to three drops of phenolphthalein indicator to this flask Titrate the standard acid KHP solution in the flask with the unknown NaOH solution To titrate the acid slowly add the sodium hydroxide from the proper buret until the solution in the Erlenmeyer flask is a faint pink color This should take from between 5 to 10 mL of base Titrate at least 3 samples of base NaOH The three samples should have molarities that are close together A good titration is one where the individual molarity values do not change by more than a few thousandths between all three titrations NaOH sample I Final Volume NaOH 22 7 Final Volume of Acid KHP 222 Initial Volume NaOH 0 00 mL Initial Volume of Acid KHP 0 00 mL Ilm of NaOH Used 22 7MLVolume of Acid KHP Used ML
