Compound: Ceric Ammonium Nitrate (CAN)
Answer
CAN is an inorganic compound with the formula (NH4)2Ce(NO3)6 , characterized by its orange/red color and solubility in water. It functions as a powerful oxidizing agent (E∼1.61 V) in organic synthesis , particularly for aromatics and dyes. Its primary advantage over other cerium (IV) reagents is its higher solubility in water (1,410 g/L at 25 ℃). In redox reactions, Ce(IV) converts to Ce(III) via a one-electron change, causing the solution color to shift from orange to a weak yellow. This compound has been specifically examined for the fast degradation of Reactive Red 31 (RR31) dye in wastewater treatment.
