Chromium Nitrate – 500 gram Packs

Chromium Nitrate is an inorganic chromium salt used in laboratory chemistry, inorganic synthesis, and materials research. A commonly supplied form is Chromium(III) Nitrate Nonahydrate, also known as Chromic Nitrate Nonahydrate, which contains chromium in the +3 oxidation state. Its chemical formula is Cr(NO₃)₃·9H₂O, and its formula mass is approximately 400.15 g/mol. This hydrated compound is commonly described as deep violet crystalline material and is readily soluble in water, making it suitable for preparing aqueous chromium(III) solutions for appropriate laboratory procedures. It is relevant to investigations involving transition-metal chemistry, coordination compounds, and the preparation of selected inorganic materials. Its suitability for a particular experiment depends on the exact chemical form, grade, and method requirements. Chromium Nitrate is an oxidizing chemical and must be handled with suitable protective equipment and kept away from combustible materials and reducing agents.
