Recall the mnemonic for redox reactions:
Loss Electrons → Oxidation → Reducing Agent
Gain Electrons → Reduction → Oxidizing Agent
This means the element that gains electrons/reduced is the oxidizing agent while the element that loses electrons/oxidized is the reducing agent.
Identify the oxidizing agent and the reducing agent in each of the following.
8 H+(aq) + 6 Cl-(aq) + Sn(s) + 4 NO3-(aq) → SnCl62-(aq) + 4 NO2(g) + 4 H2O(l)
