Which is a medium reactive metal?
Think it through first, then pick an option.
- a Au
- b Al
- c Zn
- d Hg
Answer and explanation
Correct answer: c Zn
Zn, Fe and Pb are the medium reactive metals.
Why the other options are wrong
- a Au: Au is nearly unreactive and found pure; the medium reactive one is Zn.
- b Al: Al is in the highly reactive group, extracted by electrolysis; the answer is Zn.
- d Hg: Hg is in the less reactive group, extracted by auto-reduction; the answer is Zn.
