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.----- Cu + e- --> _______________ E0 = 0.161 V Fe + e- ---> _______________ E0 = 0.767
