3 IBr + 4 NH3 → NI3 + 3 NH4Br
This is an oxidation-reduction (redox) reaction:
3 II + 6 e- → 3 I-I (reduction)
N-III - 6 e- → NIII (oxidation)
IBr is an oxidizing agent, NH3 is a reducing agent.
- IBr – Iodine monobromide
- Names: Ammonia , Azane (only intended for use in naming derivatives of ammonia) , Hydrogen nitride
- Appearance: Colourless gas ; Colourless gas or compressed liquefied gas with pungent odour ; Colorless gas with a pungent, suffocating odor. [Note: Shipped as a liquefied compressed gas. Easily liquefied under pressure.]
