How do you make nan3?

To make NaN₃ (sodium azide), sodium metal is reacted with azide ions, typically derived from ammonium azide. This reaction is performed in a controlled environment due to the compound's sensitivity and potential explosiveness. The resulting product is a white crystalline solid that can be purified through recrystallization. Proper safety precautions must be taken, as sodium azide is highly toxic and can be hazardous.
