Magnesium reacts with iron(II) chloride according to the equation
Mg(s) + FeCl2(aq) → MgCl2(aq) + Fe(s)
a. Is magnesium oxidized or is it reduced?
Magnesium is reduced.
b. Is iron(II) ion oxidized or is it reduced?
Iron(II) ion is oxidized .
c. What is the oxidizing agent?
d. What is the reducing agent?
All of your answers should be reversed.
Oxidation is the loss of electrons.
Reduction is the gain of electrons.
The substance oxidized is the reducing agent.
The substance reduced is the oxidizing agent.
Mg goes from zero oxidation state on the left to +2 on the right. That is a loss of two electrons; therefore, it is oxidized. That makes it the reducing agent.
Fe goes from +2 on the left to zero on the right; that is a gain of electrons. That makes it reduced and Fe^2+ is the oxidizing agent.
In this reaction Fe is reduced (gain of electrons/ loss of oxygen) and Mg is oxidised (loss of electrons/ gain of oxygen)
This is for Magnesium reacting with Iron II, and not Iron III.
