Ammonium chromate ((NH4)2CrO4)

Description:
Ammonium chromate, with the chemical formula (NH4)2CrO4 and CAS number 7788-98-9, is an inorganic compound that appears as a yellow crystalline solid. It is highly soluble in water, which makes it useful in various applications, including as a reagent in analytical chemistry and as a dyeing agent in textiles. The compound is known for its strong oxidizing properties due to the presence of chromium in its hexavalent state. Ammonium chromate can release ammonia gas upon heating, and it is considered hazardous due to its potential toxicity and environmental impact, particularly concerning chromium compounds. It is classified as a carcinogen and poses risks to human health and the environment, necessitating careful handling and disposal. In terms of its chemical behavior, it can participate in redox reactions and is often used in the synthesis of other chromium-containing compounds. Proper safety measures should be observed when working with ammonium chromate to mitigate exposure risks.

    Ammonium chromate

    CAS:
    Ammonium chromate is a chemical compound that contains ammonia, chromium and oxygen. It is an oxidizing agent with a wide range of industrial applications, such as in the manufacture of dyes, pigments, plastics, and wood preservatives. Ammonium chromate can be prepared by reacting hydrogen fluoride with sodium carbonate to produce ammonium carbonate and sodium chloride. The reaction is then completed by adding a mixture of potassium dichromate and hydrochloric acid to the ammonium carbonate. Ammonium chromate can also be produced by oxidizing fatty acids with nitric acid or radiation.
