Question

Oxidation and reduction processes occur simultaneously .. justify the statement

Answer 1

Hi,

 

Oxidation refers to losing of electrons while reduction refers to the gaining of electrons. The reactions in which oxidation and reduction takes place simultaneously are referred to redox reaction. For e.g.

 

CuO + H2 →  Cu + H2O

Here copper oxide is reduced and thus acts as oxidizing agent.H2 is oxidized and acts as reducing agent.

 

There are reactions in which oxidation and reduction of same compound results. Such reactions are called disproportionation reaction. For e.g. on heating potassium chlorate we get

 

2KClO3 → 2KCl + 3O2

 

The other example is

 

2H2O2 → 2H2O + O2

 

Hope it helps.

Cheers!

Answer 2

Answer:

Explain with one example. Oxidation is a losing of electrons and Reduction is a gaining of electrons. The reaction in which oxidation reduction taking place simultaneously are called as Redox reaction. In this examples copper oxide is reduced and acts as oxidizing agent and H2 is oxidized and acts as reducing agent
