Question

name the reduction agent that may be used to obtain manganese fron manganese dioxide

Answer 1

carbon is the reducing agent

Answer 2

Hii Yash,

● Answer -
Manganese can be extracted from MnO2 with aluminum powder as reducing agent.

● Explanation -
- Aluminium is more reactive than manganese, thus can reduce manganese from its oxide.
- When manganese dioxide is heated with aluminium powder, manganese metal is obtained.
3MnO2 + 4Al --> 3Mn + 2Al2O3
- Alumium oxide obtained as byproduct is removed to get clear manganese.

Hope this helps you..
