Which metal is used as a reducing agent in Smelting______?
Correct answer: A. C
- A. C
- B. Zn
- C. Al
- D. Cu
Explanation
Carbon acts as a reducing agent during smelting because it removes oxygen from metal oxides, producing the metal and carbon monoxide or carbon dioxide. The likely mistake is choosing aluminium, which is also a strong reducing agent but is mainly used in aluminothermic reduction rather than ordinary carbon smelting.

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.
