Question
In the given equation
Mg + 2HCl → MgCl2 + H₂
1 mark
- Mg is getting reduced
- Mg is getting oxidised
- Cl is getting oxidised
- H is getting oxidised
Solution
In the given equation Mg + 2HCl → MgCl2 + H2,
-
Mg is getting oxidised: In this reaction, magnesium (Mg) starts with an oxidation state of 0 and ends up with an oxidation state of +2 in MgCl2. This increase in oxidation state indicates that Mg is being oxidised.
-
Cl is getting reduced: Chlorine (Cl) in HCl starts with an oxidation state of -1 and ends up with the same oxidation state in MgCl2. Since there is no change in oxidation state, Cl is neither being oxidised nor reduced.
-
H is getting oxidised: Hydrogen (H) in HCl starts with an oxidation state of +1 and ends up with an oxidation state of 0 in H2. This decrease in oxidation state indicates that H is being reduced.
So, in this reaction, Mg is getting oxidised and H is getting reduced.
