🤓 Based on our data, we think this question is relevant for Professor Ballantyne & Zimmer-De Iuliis' class at TORONTO.
Recall: In a redox reaction, the oxidizing agent is reduced (gains electrons) while the reducing agent is oxidized (loses electrons).
For Al: The oxidation state of Al went from 0 to +3, which means it lost electrons and is oxidized.
Identify the oxidizing agent and the reducing agent for the following reaction:
2Al(s) + 3Sn2+(aq) → 2Al3+(aq) + 3Sn(s)
