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
