The most powerful reducing agent in aqueous solution is:
AChlorine gas
BLithium metal
CFluorine gas
DHydrogen gas
Answer & Solution
Correct answer: B. Lithium metal
1. Lithium has the lowest standard electrode potential listed.
2. So the metal gives up its electron most readily of all.
3. That makes lithium metal the most powerful reducing agent.
