Question

PLEASE GO THROUGH AND HELP ME. 

-the concentration of standard sodium thiosulphate solution is 0.01152 M.

 -the temperature of the equilibrium mixture in degree Celsius is 20oC.

In Determination #1:

Volume of thiosulphate = 32.50 mL

Volume of Aqueous aliquot = 10.15 mL

Strength of Thiosulphate = 0.01152 M

In Determination #2:

Volume of thiosulphate = 32.50 mL

Volume of Aqueous aliquot = 10.23 mL

Strength of Thiosulphate = 0.01152 M

In Determination #3:

Volume of thiosulphate = 32.67 mL

Volume of Aqueous aliquot = 10.31 mL

Strength of Thiosulphate = 0.01152 M

Part 1 - Titration of the Aqueous Layer Question 3 A student performed three aqueous layer titrations in Part 1 and they reported the following measurements: Determination #1 Determination #2 Determination #3 Final Burette 13.16 mL 33.31 mL 43.62 mL Reading Initial Burette 3.01 mL 23.08 mL 33.31 mL Reading Volume of Aqueous Aliquot 10.15 mL 10.23 mL 10.31 mL Final Burette 32.79 mL 33.25 mL 33.01 mL Reading Initial Burette 0.29 mL 0.75 mL 0.34 mL Reading Volume of Sodium 32.50 mL 32.50 mL 32.67 mL Thiosulfate 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.
