2.
b. Concentration of the iodine solution, using the formula M1*V1 = M2*V2 (where V1 and V2 are the volumes of the two concentrated chemical solutions added to the flask)
Molarity of the iodine solution (Part I):
M1V1= M2V2
M2= (0.002839M * 10.0 mL) / 12.35 mL
= 0.002299 M
3. From your two or more best "fine" titrations, calculate the average iodine concentration, thus determining today's standard value for the iodine solution
=12.40 mL+ 12.35 mL +12.35 mL
=12.3667 mL |
