Ceric ammonium nitrate (CAS 16774-21-3) is a compound with the chemical formula CeH8N6O18. It is a yellow-orange crystalline solid that is highly soluble in water. Ceric ammonium nitrate is commonly used as an oxidizing agent in various chemical reactions, particularly in organic synthesis. ...
The two compounds that go into this experiment are ammonium nitrate and potassium chloride. Where can you get your hands on these materials? Instant cold packs use ammonium nitrate and water to start an endothermic reaction. The potassium chloride can be found in the grocery store as a table s...
ammonium nitrate: A colourlesscrystalline solid, NH4NO3; r.d. 1.72;m.p. 169.6°C; b.p. 210°C. It is verysoluble in water and soluble inethanol. The crystals are rhombicwhen obtained below 32°C andmonoclinic above 32°C. It may bereadily prepared in the laboratory bythe reaction of...

Without induced vertical mixing or displacement of plume water with oxic groundwater from upgradient sources, the main mass of NH4+ could reach a discharge area without substantial reaction long after the more mobile wastewater constituents are gone. Multiple approaches including in situ isotopic ...

The mechanism of action in electroplating involves the reduction of AMMONIUM CHROMATE to chromium ions, which then undergo a redox reaction to form a chromium coating on the metal substrate. Storage Conditions: Store in a cool and dry place, away from heat and direct sunlight. View all ...
By means of spectrophotometry (Perkin-Elmer Lambda 35, Arden, NC, USA), the nitrate (NO3−) and ammonium (NH4+) concentrations were determined. There were at least three measurements of the aquifer media and groundwater parameters for all of them. Afterwards, the average was obtained for ...
