At which electrode the reduction of the solution is occurring in Al-Ag cell_____________?
Correct answer: B. Ag
- A. A
- B. Ag
- C. Both
- D. Neither
Explanation
In an Al-Ag galvanic cell, aluminium is more readily oxidised and acts as the anode, while Ag+ ions are reduced at the silver cathode. Reduction always occurs at the cathode, so the Ag electrode is the site of reduction. Students often choose Al because it is the more reactive metal, but reactivity makes it the oxidation electrode, not the reduction electrode.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
