The reducing agent is oxidized during a redox reaction

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

3 basic theories explain this Redox concept:

1. Binding/release of oxygen

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

For example:

2SO₂ + O₂ ----> 2SO₃

The reduction reaction is the release of oxygen from a substance.

For example:

2CuO → 2Cu + O₂

2. Electron release / binding reaction

Oxidation is an electron release event

Example:

2F ---> 2Fe³⁺ + 6e⁻

The reduction is an electron capture event

Example:

3O₂ + 6e⁻ ---> 3O²⁻

3. The reaction of addition/reduction of oxidation number

Oxidation is an increase/increase in oxidation number, while reduction is a decrease/decrease in oxidation number.

In this reaction, it is also known

Reducing agents are substances that experience oxidation

The oxidizer is a substance that is reduced

Let's look at the answer choices

The reducing agent is reduced.

This statement is wrong because the reducing agent undergoes oxidation

The reducing agent is oxidized.

This statement is true

The reducing agent remains unchanged.

The statement is wrong because the oxidation number of the oxidized compound will increase

The reducing agent gains electrons.

The statement is wrong because the reducing agent releases electrons

So the correct statement is B The reducing agent is oxidized

chemical reactions are an oxidation-reduction reaction

So, to determine the number of neutrons in atom, we only have to subtract the number of protons from the mass number. Take note that the nucleus of an atom is composed of protons and neutrons. And the number of particles present in the nucleus is referred as mass number (Also, called as atomic mass).
