Answer to Question #210720 in General Chemistry for Ara_

Question

Differentiate oxidation reactions from reduction reactions 

Answer 1

1) Oxidation reaction : Oxidation is a reaction that involves the addition of oxygen or loss of hydrogen or electrons.

Examples : `Cu_((s))+O_(2(g))overset("Heat")rarr 2CuO_((s))`

`underset("(sodium)")(Na)-1e^(-) rarr underset("(sodium ion)")(Na^(+))`

2. Reduction reaction : The process in which a substance loses oxygen or gains hydrogen or electrons is known as reduction.

Examples : `CuO_((s))+H_(2(g))overset("Heat")rarr Cu_((s))+H_(2)O_((g))`

`underset("(chlorine)")(Cl)+l e^(-) rarr underset("(chloride ion)")(Cl^(-))`
