Example 6. Exactly 0.4 faraday electric charge is passed through three electrolytic cells in series, first containing AgNO3, sec- ond CuSO4 and third FeCl3 solution. How many gram of each metal will be deposited assuming only cathodic reaction in each cell? Thanatbodia. cy,

Enter electrons as e". A voltaic cell is constructed in which the anode is a Ag Ag" half cell and the cathode is a Hg Hg* half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coeficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is: The cathode reaction is: The net cell reaction is: In the external circuit, electrons migratel the AgAg" electrode v the Hg Hg* electrode. In the salt bridge, anions migrate| v the Hg|Hg" compartment| v the AgAg" compartment. +

A galvanic cell consists of a Fe electrode in a 1.0 M FeSO4 solution and a Ni electrode in a 1.0 M NiSO4 solution. Calculate the Eocell at 25°C. -0.19V 0.19V -0.69V 0.69V

5) For this problem refer to the electrochemical cell below a) Which electrode is the cathode and which is the anode? b) Is this cell electrolytic or galvanic? Explain. c) If the concentration of dissolved zinc ions were increased, how would this change the measured voltage? Volumeter so so; Znisi - Zntag) - 2e Cagl + 2e -Cuis)
