1. Write the balanced oxidation and reduction half reactions forthe reaction of As2O3^(3-) and I2. What ion is oxidized and whation is reduced?
2. Assuming that 5 mL of 0.006 M arsenite solution is subjectedto coulometric titration as described in this laboratory using acurrent of 30 mamps. Calculate the time that the current should beapplied to reach the endpoint of the titration.
