Is 2H2+O2=2H2O a redox reaction?

Dennis Leppin  Follow

Yes it is a redox reaction.

Because as we know that oxidation occurs when oxygen is added and reduction takes place when hydrogen is added.

Here in this example [math]Oxygen[/math] is added to [math]Hydrogen[/math].

And [math]Hydrogen[/math] is also added to [math]Oxygen.[/math]

Means hydrogen is oxidised to form water.

And oxygen is getting reduced to form water.

Hope you understand………:-):-):-):-)

yes it is. oxidation means increase inn oxidation number and reduction means decrease in oxidation number. now here in this reaction hydrogen and oxygen being in molecular state has by default oxidation number as 0(zero). but in water the oxidation number of oxygen is -2 and that of hydrogen is +1. so ON of oxygen decreases hence undergoes reduction, and ON of hydrogen increases so undergoes oxidation. hence it is a redox reaction.
