A cell is constructed using `Cu^(2+)//Cu` and `AI^(3+)//AI` electrode what is the net cell reaction

Text Solution

AI Generated Solution

To find the net cell reaction for a cell constructed using the `Cu^(2+)//Cu` and `Al^(3+)//Al` electrodes, we need to identify the oxidation and reduction reactions occurring at each electrode. ### Step-by-Step Solution: 1. **Identify the Half-Reactions**: - The reduction half-reaction occurs at the cathode (where reduction takes place). - The oxidation half-reaction occurs at the anode (where oxidation takes place). ...
