Question

In the given reaction,
$2K_4\left[Fe{\left(CN\right)}_6\right]\left(aq\right)+H_2{O}_2\left(aq\right)⟶2K_3\left[Fe{\left(CN\right)}_6\right]\left(aq\right)+2KOH\left(aq\right)$
Which of the following processes takes place?

• A. Oxidation due to removal of potassium
• B. Oxidation due to removal of iron
• C. Reduction due to removal of potassium
• D. Oxidation due to removal of electronegative element

Answer 1

The correct option is A Oxidation due to removal of potassium

In the following reaction the oxidation number of the Iron in its co-ordination compound changes from +2 to +3 i.e there is a increase in its oxidation number the compound undergoes oxidation reaction. The corresponding change is observed due to reaction between counter-ion of co-ordination compound and $H_2{O}_2$ to form $KOH$.
