7. You decide to construct a zinc/aluminum galvanic cell in which the electrodes are connected by a wire and the solutions are connected with a salt bridge. One electrode consists of an aluminum bar in a 1.0 M solution of aluminum nitrate. The other electrode consists of zinc bar in a 1.0 M solution of zinc nitrate. Draw the complete electrochemical cell diagram and use it to answer the questions that follow. a. Which electrode is the cathode and which...

c) Fe/0.1 M FeSO4//0.1 M CuSO4/Cu
I soaked a porous cup in tap water for a few minutes and then i
let it stand in a 100 ml beaker containing 10ml of 0.1 M FeSO4. I
added enough 0.1M CuSO4 to the cup until the two liquid levels were
the same height. I inserted a zinc strip into the 0.1 M FeSO4 and a
shiny copper strip into the 0.1 M CuSO4. I connected the...
salt bridge ME Cr(s) electrode Cu(s) electrode 1.0 M Cr3+ (aq) 1.0 M Cu2+ (aq) A electrolytic cell similar to that shown in the figure above is constructed. The electronic device shown at the top of the figure is a power supply. One electrode compartment consists of a chromium strip placed in a 1.0 M CrCl3 solution, and the other has a copper strip placed in a 1.0 M CuSO4 solution. The overall cell reaction is: 2 Cr3+ (aq) +...
Sketch the galvanic cells based on the following half-reactions. Show the direction of electron flow, show the irection of ion migration through the salt bridge, and identify the cathode and anode. Give the overall balanced equation and determine E knot for the galvanic cells. Assume that all concentrations are 1.0 M and that all partial pressures are 1.0 atm. a. H2O2 + 2H+ + 2 e- -> 2H2O (E knot= 1.78 V) O2 + 2H+ + 2e- -> H2O2 (E...

Cher 103A Electrochemistry -- which of the two diagrams below represents the galvanic cell? The electrolytic cell? How can you tell? Voltmeter Power supply Molten MX D a. For the galvanic cell if the cathode is on the left and the anode is on the right, which direction do the electrons flow? b. For the electrolytic cell in problem 4, where is the cathode, on the left or the...
Hi. can some one please explain me the solution for
this question. the correct answer is B. thanks.
8. Consider the following concentration cell. Ag (aq) + e → Ag(s) E = 0.80 V 0.1 M Ag Which one of the following statements is TRUE? a) The electrode on the left containing 1 M Ag (aq) is the anode. b) Equilibrium occurs when the [Ag (aq) in both cells is equal. c) The initial reading on the voltmeter would be...
Can someone explain this question for me?
I understand I have to find an action potential, Q value and use
a Nernst equation, but I can not actually apply those into a
question.
Thanks
Part A Calculate the cell potential of a concentration cell that has solid zinc and Zn 0.210 M for the cathode, and solid zinc and 2+ 0.038 M for the anode.
