We’re being asked toidentify the oxidizing and reducing agentsin the given reactions:
a) 4 Li(s) + O2(g)→2 Li2O (s)
b) Mg(s) + Fe2+(aq)→Mg2+(aq) + Fe(s)
To do so, we need to identify thechange in oxidation statefor each element in the reaction.
Recall the mnemonic for redox reactions:
This means the element thatgains electrons/reducedis theoxidizing agentwhile the element thatloses electrons/oxidizedis thereducing agent.
Identify the oxidizing agent and the reducing agent for
4Li(s) + O2(g) → 2Li2O (s)
Mg(s) + Fe2+(aq) → Mg2+(aq) + Fe(s)
