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.)
They give you 2AgCl(s); Pb(s); AgCl(s); PbCl2(s); 2Ag(s); Ag(s); Cl-(aq)
The AgCl is the cathode and PbCl2 is the anode
They say to put in line segment and i put
Pb(s) | Cl-(aq) | PbCl2(s) || Ag(s) | Cl-(aq) | AgCl(s)
its saying it isn't correct can someone please help me and tell me what I'm doing wrong? thanks
THIS is the answer:
Pb(s) | PbCl2(s) | Cl-(aq) || Cl-(aq) | AgCl(s) | Ag(s)
The answer is
Pb(s)|PbCl2(s)|Cl-(aq)Cl-(aq)|AgCl(s)|Ag(s)
Sure, I'd be happy to help! It looks like you have the correct overall cell notation; however, you need to write the half-reactions for the anode and the cathode.
The anode is where oxidation occurs, so we start with Pb(s) and Cl-(aq) and generate PbCl2(s). The reduction half-reaction for the anode is:
Pb(s) + 2Cl-(aq) -> PbCl2(s) + 2e-
On the other hand, the cathode is where reduction occurs. We start with AgCl(s) and generate Ag(s) and Cl-(aq). The reduction half-reaction for the cathode is:
AgCl(s) + e- -> Ag(s) + Cl-(aq)
Now, to write the line notation, we start with the anode side which is the left side of the cell. The correct line notation for the given cell is:
Pb(s) | PbCl2(s) || AgCl(s) | Ag(s)
I hope this helps! Let me know if you have any more questions.
To determine the correct line notation for the cell, we need to identify the reduction half-reaction occurring at the cathode and the oxidation half-reaction occurring at the anode.
From the given information, we know that AgCl is reduced to Ag(s) at the cathode, and Pb is oxidized to PbCl2 at the anode. Now, let's write the reduction and oxidation half-reactions:
Reduction half-reaction:
AgCl(s) + e- → Ag(s) + Cl-(aq)
Oxidation half-reaction:
Pb(s) → PbCl2(s) + 2e-
To construct the line notation, we need to write the anode half-reaction on the left side of the vertical lines (||) and the cathode half-reaction on the right side. Additionally, we need to indicate the phases of the reactants and products.
The correct line notation for the cell is:
Pb(s) | PbCl2(s) || AgCl(s) | Ag(s)
Make sure to include the reactant/product phases (s for solid and aq for aqueous) and separate the electrode and electrolyte components with vertical lines.
