Highly electropositive metals are best produced by
- A. electrolytic methods
- B. reduction with carbon of their oxides
- C. straight thermal decomposition of salts
- D. reduction of their halides by hydrogen
Step-by-step solution
Highly electropositive metals (e.g., Na, K, Mg, Ca) have very high reduction potentials, making them strong reducing agents. Chemical reducing agents like carbon or hydrogen are insufficient to reduce their compounds. Electrolysis of molten salts provides the necessary energy to overcome their high ionization energies, making it the only practical method for production.
