What happens to a reducing agent during a redox reaction?
2 answers:
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
the reduction process
an element's oxidation
an element's oxidation number increase
Keywords: oxidation, reduction, The oxidation number

Explanation:
Hello,
In this case, for the described chemical reaction:
2 HCl(aq) + Mg(OH)2(aq) → MgCl2(aq) + 2 H2O(l)
We can notice there is a 2:1 molar ratio between the moles of hydrochloric acid and magnesium hydroxide, therefore, at the equivalence point:
And in terms of volumes and concentrations we verify:
So we use the given data to proof it:
Therefore, we can conclude the data is wrong by means of the 2:1 mole ratio that for sure was not taken into account. This is also supported by the fact that normalities are actually the same, but the nomality of magnesium hydroxide is the half of the hydrochloric acid normality since the acid is monoprotic and the base has two hydroxyl ions.
Best regards.
