- A \(\mathrm{K}_{4}\left[\mathrm{Fe}\left(\mathrm{CN})_{6}\right]\right.\)
- B \(\mathrm{K}_{3}\left[\mathrm{Fe}\left(\mathrm{CN})_{6}\right)\right.\)
- C \(Fe(CNS)_{3}\)
- D \(Fe_{4}[Fe(CN)_{6}]_{3}\)
Answer & Solution
Correct Answer
(D) \(Fe_{4}[Fe(CN)_{6}]_{3}\)
Step-by-step Solution
Detailed explanation
Ferric ion forms a prussian blue precipitate due to the formation of \(\mathrm{Fe}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]_{3}\). This complex is formed during the determine action of presence of nitrogen in the given sample. In this method, to portion of sodium fusion…
