Question

3MnO2 + 4Al → 3Mn + 2Al2O3 which is reducing and oxidizing...and give me the reason​

Answer 1

Answer: The reducing agent here is 4Al.

The oxidizing agent here is 3MnO2.

• This is because 3MnO2 is reduced to 3Mn by 4Al , so reducing agent is 4Al.
• 4Al is oxidized to 2Al2O3 by 3MnO2, so oxidizing agent is 3MnO2.
