identify the substance undergoes oxidation and reduction of following 3Mno2 plus 4Al gives 3Mn plus 2Al2O3 plus heat
Answers
Substance which is getting :-
☸️ Oxidised- Aluminium
☸️ Reduction - Manganese di oxide.
OXIDATION :-
oxidation is the process in which either oxygen is added to an element or hydrogen is removed from the element.
OXIDIZING AGENT :-
The agent due to which oxidation occurs is known as oxidising agent.
An oxidizing agent itself undergoes reduction.
REDUCTION :-
The process by which hydrogen is added to an element or oxygen is removed from an element is known as reduction.
REDUCING AGENT :-
The agent due to which reduction takes place is known as reducing agent.
A reducing agent itself undergoes oxidation.
So,
In the given equation :-
☸️ manganese dioxide is getting reduced to manganese.
This is due to the presence of aluminium which is the reducing agent in the reaction.
☸️ Aluminium is getting oxidised to Aluminium oxide.
This is due to the presence of manganese dioxide which is leading to the oxidation of aluminium.
Therefore, manganese dioxide is oxidizing agent.
