9. When determining Fe3 ions in wastewater by amperometric titration with a solution of tin chloride SnCl2 with a molar concentration equivalent of 0.0100 mol/dm3, the following results were obtained:
V(SnCl2), cm3 2 4 6 8 10 12 14 16
Jd, μA 10 10 10 10 10 25 40 55
Plot the titration curve and calculate the content of Fe3 in mg/dm3 if 100.00 cm3 of water was taken for titration.
