How is Calcium Nitride Prepared
It can be synthesized when calcium is heated at an elevated temperature in the presence of air, which is represented by the following direct reaction of the elements :
3Ca + N2 → Ca3N2
The calcium nitride formed can be easily identified, as it reacts with moisture or water to produce calcium hydroxide and ammonia :
Ca3N2 + 6H2O → 3Ca(OH)2 + 2NH3
