\mathrm{Fe}^{3+}

cation gives a Prussian blue precipitate on addition of potassium ferrocyanide solution due to the formation of:

View answer and explanation

Correct option: D

\mathrm{Fe}_4\left[\mathrm{Fe}(\mathrm{CN})_6\right]_3

The correct answer is D (

\mathrm{Fe}_4[\mathrm{Fe}(\mathrm{CN})_6]_3

) because Prussian blue is formed by the reaction of

\mathrm{Fe}^{3+}

with ferrocyanide ions, resulting in this specific complex.
