Overview: A chemistry video detailing the synthesis of sodium azide (and mentions potassium azide) from hydrazine sulfate. Conceptually, it covers converting the hydrazine salt into free hydrazine in an alcoholic solvent, then performing a controlled reaction with an organic nitrite (isopropyl nitrite) in a closed, cooled apparatus to form sodium azide. The product is isolated by solvent extractions and drying to yield a fine white powder. The presenter emphasizes safety concerns: azides are highly toxic and explosive, requiring dry reagents and apparatus, avoidance of acids and chlorinated solvents, careful handling of fumes, and that even small exposures can be dangerous. The video also references related reagents (e.g., hydroxides) and mentions channel updates and a donation plan.
