Which substance loses electrons in a chemical reaction?
a)the one that is oxidized, which is the oxidizing agent
b)the one that is reduced, which is the reducing agent
c)the one that is oxidized, which is the reducing agent
d)the one that is reduced, which is the oxidizing agent

The reducing agent is a substance loses electrons in a chemical reaction

The oxidation-reduction reaction or abbreviated as a redox is a chemical reaction in which there is a change in oxidation number

3 basic theories explain this Redox concept:

The oxidation reaction is the binding of substance with oxygen. (O₂)

For example:

2SO₂ + O₂ ----> 2SO₃

The reduction from oxygen from a substance.

For example:

2CuO → 2Cu + O₂

Oxidation is an electron release event

Example:

2F ---> 2Fe³⁺ + 6e⁻

The reduction is an electron capture event

Example:

3O₂ + 6e⁻ ---> 3O²⁻

Oxidation increases in oxidation number, while reduction is a decrease in oxidation number.

We see the answer choices :

The oxidizer is a substance that is reduced, so it's a false statement

Reducing agents are substances that experience oxidation, so wrong statements

The statement is true because the Oxidation is an electron release event and occurs in the reducing agent

The statement is wrong because the reduction process is electron capture so the oxidation number drops

chemical reactions are an oxidation-reduction reaction

the reduction process

an element's oxidation

an element's oxidation number increase
