Electrochemical Cells: Line Notation

Question

Write the cell notation for an electrochemical cell consisting of an anode where Al (s) is oxidized to Al³⁺ (aq) and a cathode where Cu²⁺ (aq) is reduced to Cu (s) . Assume all aqueous solutions have a concentration of 1 mol/L.

________

Answer 1

By convention, anode is on the left and cathode is on the right. | represents separation of electrode from solution and || represents the salt bridge.

Al(s) | Al³⁺(aq, 1 M) || Cu²⁺(aq, 1 M) | Cu(s)
