Question

Consider the following chemical reaction.

MnO₂ + 4 HCl ------> MnCl₂ + Cl₂ + 2H₂O

Which is the oxidising agent and which one is the reducing agent ?

Which substance is getting oxidised and which substance is getting reduced ?

explain your answer ????

Answer 1

Hello friend

Reduction is a reaction that involves the addition of hydrogen or removal of oxygen

Oxidation is addition of oxygen or removal of hydrogen

Here MnO2 is reduced and HCl is oxidised.

Oxidizing agents, or also called oxidants, gain electrons and get reduced in a chemical reaction.

Reducing agents are the ones which get oxidised in a chemical reaction

MnO2 is the oxidising agent and and HCl is the reducing agent.

Answer 2

Heya,

Here is the answer:-

MnO₂ + 4 HCl ------> MnCl₂ + Cl₂ + 2H₂O

Oxidation:- It is a process in which either oxygen is added to a substance or hydrogen is removed from the substance.

Reduction:- It is a process in which either hydrogen is added to a substance or oxygen is removed from a substance.

Oxidising agent:- A substance which gives oxygen or removes hydrogen for oxidation

Reducing agent:- A substance which gives hydrogen or removes oxygen for reduction.

Here from this chemical equation we can get the following information;

Substance oxidised:- Hcl because Hydrogen is being removed from it.

Substance reduced:- MnO₂ because Oxygen is being removed from it.

Oxidising agent:- MnO₂ because it gives out oxygen for oxidation.

Reducing agent:- Hcl because it gives out hydrogen for reduction.

Tips to remember:-
1. Always substance  oxidised is the same as reducing agent and substance reduced is same as oxidising agent.
2, Always for writing agents and substances oxidised and reduced we should make use of only reactants and not products .

Hope it helps u...
