Question

Complete the two reduction half reactions for the cell shown at the right, and show the line notation for the cell by dragging labels to the correct position. (The electrode on the left is the anode, and the one on the right is the cathode.) Anode half-reaction: +2e^- equivalent 2CL^- Cathode half-reaction: +2e^- equivalent 2CL^- Line notation:

Answer 1

Oxidation of lead chloride occurs at anode The anode half-reaction is as follows: PbCl2 (s) 2ePb(s) +2CI Reduction of silver chloride occurs at cathode, The cathode half-reaction is as follows: 2AgCI(s) +2e-근 2Ag (s) +2C1-

In general, the oxidation cell (anode) is placed on left side and the reduction half cell (cathode) is placed on left side of the cell diagram. Line natation: The components of the anode compartment (oxidation half-cell) are written to the left of the components of the cathode compartment (reduction half-cell) A single vertical line represents a phase boundary. A comma separates the half-cell components that are in the same phase Half-cell components usually appear in the same order as in the half-reaction, and electrodes appear at the far left and right of the notation A double vertical line indicates the separated half-cells and represents the phase boundary on either side of the salt bridge. The overall cell reaction is as follows: 2AgCI(s) +Pb(s)2Ag (s)+PbCl (s) Line notation for the given cell is as follows: Pb (s) | PbC12(s) ll AgCl(s) | Ag(s)

Answer 2

Oxidation of lead chlori de occurs at anode. The anode half reacti on is as follows: PbCl2 (s) + 2 e-- Reduction of silver chl onide occurs at cathode The cathode reacti on is as follows: Pb (s) + 2 Cl- In general, the oxi dation cell (anodic) is placed on left side and the reduction half cell (cathode) is placed on left si de of the cell diagram. Line notati on The components of the anode compartment (oxidation half cell) are written to the left of the components that are in the same phase Half cell components usually appear in the same order as in the half reaction, and electrode appear at the far left and right of the notation a double verticle line indicates the seperated half cells andrepresents the phase boundary on eiher si de of the salt bridge. line notation for the complete reaction is as follows Pb (s)|PbC12 (s)|CI(aq) || Cl (aą) IAgCI(s)|Ag(s)
