Ferric Nitrite

Ferric Nitrite (chemical formula Fe(NO2)3) is an iron(III) compound where iron is in the +3 oxidation state and is bonded to nitrite ions (NO2−). It is less commonly encountered than ferric nitrate and is typically characterized as an unstable, pale yellow to orange crystalline solid or solution. The compound is soluble in water and may decompose relatively quickly due to the instability of the nitrite ion under oxidative conditions.

Ferric nitrite is mainly of interest in chemical research and specialized applications involving coordination chemistry or nitrite-based reactions. It is not widely available commercially compared to other iron salts like ferric nitrate or ferric sulfate.

Key Details:

Chemical formula: Fe(NO2)3

Appearance: Pale yellow to orange crystals or solution

Solubility: Soluble in water

Stability: Relatively unstable, decomposes under light/heat

Applications: Research chemical, reagent in nitrite coordination studies

Because ferric nitrite is a less common and less stable iron(III) salt, specific commercial grades like “extra pure” may not be readily available or widely documented. Where used, it requires careful handling with proper storage conditions to prevent decomposition.
