ions form an intense Prussian blue precipitate when reacted with potassium hexacyanidoferrate(II). T — Qualitative and Quantitative Analysis Chemistry Question
Question
$Fe^{3+}$ ions form an intense Prussian blue precipitate when reacted with potassium hexacyanidoferrate(II). The chemical formula representing Prussian blue is:
Answer: B
💡 Solution & Explanation
The reaction is $4Fe^{3+} + 3[Fe(CN)_6]^{4-} \rightarrow Fe_4[Fe(CN)_6]_3 \downarrow$. The resulting complex is Iron(III) hexacyanidoferrate(II), widely known as Prussian blue.
