About Ammonium Dichromate

Ammonium Dichromate is a highly toxic, bright orange-red crystalline solid widely recognized for its acidic pH and powerful oxidizing properties. Its unique structure, consisting of ammonium and dichromate ions, makes it an effective reagent in industrial oxidation processes, pyrotechnics, and analytical chemistry as a reliable oxidizing agent. When heated, it decomposes, releasing nitrogen gas and chromic oxide. It is odorless with a bitter metallic taste and exhibits excellent solubility in water, while being slightly soluble in alcohol. With a molecular weight of 252.06 g/mol and a density of 2.15 g/cm, it is stable under recommended storage conditions but is highly sensitive to flammable substances and heat sources. Ideal for catalytic applications, its purity exceeds 98%. Ammonium Dichromate is commonly utilized as teaching material for decomposition reactions and the production of fireworks. Users must exercise caution due to its highly toxic nature, ensuring careful handling and safe storage in a dry, cool, and well-ventilated environment.
