A student performed three aqueous layer titrations in Part 1 and they reported the following measurements: Final Burette Reading Initial Burette Reading Volume of Aqueous Aliquot Final Burette Reading Initial Burette Reading Volume of Sodium Thiosulfate Determination #1 16.33 mL 6.50 mL 9.83 m 31.98 mL 0.76 mL 31.22 mL Determination #2 Determination #3 26.76 mL 16.33 mL 10.43 mL 33.62 mL 0.88 mL 32.74 mL 36.95 mL 26.76 mL 10.19 mL 32.22 mL 0.41 mL 31.81 mL Which determinations were the student's 'best two'? Calculate the percent difference for the 'best two' and show the complete calculation. Note that the concentration of standard sodium thiosulfate, which the student used, is unknown.

Phenolphthalein is a commonly used indicator that is colorless in the acidic form (pH 8.3) and pink in the base form (pH 10.0). It is a weak acid with a pKa of 8.7. What fraction is in the acid form when the acid color is apparent? What fraction is in the base form when the base color is apparent?
5. A 300.0 mg sample containing Na,CO3, NaHCO, and NaOH and inert material either alone or in some combination was dissolved and titrated with 0.1000 M HCI the titration required 24.41 ml to reach the phenolphthalein endpoint. And an additional 8.67 mL to reach the methyl red endpoint. Determine the composition of the sample and calculate the percent of each titrated component.
