You are titrating 100.0 mL of 0.0200 M Fe3 in 1 M HClO4 with 0.100 M Cu to give Fe2 and Cu2 using Pt and saturated Ag | AgCl electrodes to find the endpoint. (a) Write the balanced titration reaction. (b) Complete the two half reactions for the Pt electrode. (c) Write two correct Nernst equations for the cell voltage. (Each applying at different points in the titration.). E^o of the Ag |AgCl electrode is 0.197 V. (d) Calculate the values of E for the cell when the following volumes of the Cu titrant have been added 1ml, 10ml, 18.5ml, 20ml.
