Determine whether each of the following changes representsoxidation or reduction.

You are watching: Determine whether each change represents oxidation or reduction.

C2H6O to C2H4O2

Ketone to Alcohol

Fe^3+ come Fe^2+

Cu to Cu^2+

C6H12O6 come CO2

2Ag^+ to 2Ag

CH3CH2OH to CH3CH3

NO^3- come NO^2-


Oxidation and reduction is varieties of chemistry reactions in i m sorry involve a deliver of electron from one atom come another. Oxidation-reduction reactions are carrying ~ above by ns or gain of electrons. The oxidized varieties can be established by recognize the oxidation number of chemical species.

Oxidation and reduction deserve to be explained in 3 ways:

In regards to oxygen

In regards to hydrogen

In terms of electrons


In regards to oxygen:

The get of oxygen is called oxidation. Because that example,

*

The loss of oxygen is called reduction. For example,

*
2Cu+CO,Loss oxygen" />

In terms of hydrogen:

The ns of hydrogen is dubbed oxidation. Because that example,

*

The get of hydrogen is referred to as reduction. For example,

*

In regards to electron:

Oxidation: ns of electrons is called oxidation.

*

Reduction: gain of electrons is called reduction.

*


*

*
is oxidized to
*

Ketone come alcohol

For example:

*
R,CHOH" />

*
Fe2+" />

Fe(III) is diminished to Fe(II).

*
Cu2+ 2e" />

Cu is oxidized to Cu2+

The oxidation state that Cu increased from 0 come +2. Therefore, this is oxidation reaction.

C6H12O6 come CO2

H is +1 oxidation state and O is -2 oxidation states.

Oxidation state that C is 6x + 12(+1) + 6(-2) = 0, x = 0.

For CO2, C is +4 oxidation states.

2Ag" />

Ag+ decreased to Ag.
