Question

Out of mn3+ and cr3+ which is more strong oxidising and why

Answer 1

out of mn3+ and cr3+,mn3+ is a stronger oxidising agent because it has 4 electrons in its valence shell and when it gains one electron to form Mn

Answer 2

Out of $Mn^{3+}$ and $Cr^{3+}$, $Mn^{3+}$ is more oxidizing.

Explanation:

• The $E^0$ for $Cr^{3+}/Cr^{2+}$ is negative and the value is -0.41V.

• On the other hand the $E^0$ for $Mn^{3+}/Mn^{2+}$ is positive and the value is +1.57V.

• As the $E^0$ value for Cr ions is negative, the $Cr^{2+}$ ion can easily undergo oxidation to give $Cr^{3+}$ ion. Thus it is a strong reducing agent.
• As the $E^0$ value for Mn ions is positive, the $Mn^{3+}$ ion can easily undergo reduction to give $Mn^{2+}$ and hence acts as strong oxidizing agent.
• Thus it is inferred that out of $Mn^{3+}$ and $Cr^{3+}$, $Mn^{3+}$ is more oxidizing.
