Prussian Blue Formula
Prussian blue is a dark blue pigment that has the chemical formula Fe3[Fe(CN)6]4. Let's break down the formula and understand its composition.
Iron (Fe)
- Prussian blue is primarily composed of iron (Fe) ions. In this compound, there are multiple iron ions present.
Cyanide (CN)
- Cyanide (CN) is a polyatomic ion that consists of one carbon atom (C) and one nitrogen atom (N). In the formula of Prussian blue, cyanide ions are present.
Prussian Blue Formula Breakdown
- Prussian blue has the formula Fe3[Fe(CN)6]4. Let's break it down further:
1. Fe3: This indicates that there are three iron ions present in the compound.
2. [Fe(CN)6]4: This represents a complex ion formed by one iron ion (Fe) bonded to six cyanide ions (CN). The 4 denotes that there are four of these complex ions.
Explanation of Correct Answer (Option D)
The correct formula for Prussian blue is Fe3[Fe(CN)6]4, which is denoted by option D.
Option A (Fe3[Fe(CN)6]2) is incorrect because it suggests that there are only two complex ions of [Fe(CN)6], whereas the correct formula indicates four.
Option B (Fe2[Fe(CN)6]3) is incorrect because it suggests that there are three complex ions of [Fe(CN)6], whereas the correct formula indicates four.
Option C (Fe4[Fe(CN)6]3) is incorrect because it suggests that there are three complex ions of [Fe(CN)6], whereas the correct formula indicates four.
Therefore, the correct formula for Prussian blue is Fe3[Fe(CN)6]4, as indicated in option D.
