Given the following pair of halfreactions fill in the line n
Given the following pair of half-reactions, fill in the line notation for a standard cell using these two half-reactions.
Since it is a standard cell, all concentrations will be 1 M, so do not enter concentrations.
You have solid platinum (Pt) electrodes to use, where necessary.
Do not include the physical state of the components, i.e., solid platinum would just be Pt.
For subscript and superscripts use the model: Ag+ would be Ag^+ and SO42- would be entered as SO4^2-, with the \"^\" character indicating a superscript.
Leave a space between components.
| Tl+ (aq) + e- Tl (s) | o = -0.34 | |
| Au3+ (aq) + 3e- Au (s) | o = 1.50 |
Solution
Since Tl has higher reduction potential than Au, hence Tl is anode and Au ios cathode.
The cell notation begins with the oxidation reaction || reduction reaction:
Answer: Tl | Tl^+ || Au^3+ | Au
