Ammonium dichromate upon heating decompo...

Ammonium dichromate upon heating decomposes to give nitrogen gas and chromium oxide is it a redox reaction ?
If so what is the type of the redox whether inter or introamolecular

Text Solution

Verified by Experts

Hre O.N of N increase from -3 to 0 in `N_(2)` therefore it is oxidised in contrast the O.N of Cr decrease from +6 to +3 in `Cr_(2)O_(3)` therefore it is reduced thus it is an interamolecular redox reaction since both the species cation and the anion are part of the same compountd ammonium dichromate
