Sodium hydrazoate, NaN₃

The Sodium hydrazoate, NaN₃ is formed by neutralizing hydrazoic acid with sodium hydroxide; by the interaction of sodamide and nitrous oxide:



and by decomposing hydrazoyl chloride with sodium hydroxide:

N₃Cl+2NaOH =NaN₃+NaOCl+H₂O.

Sodium hydrazoate forms colourless crystals, which melt without decomposition, but explode at a temperature higher than the melting-point. At 10° C. 100 grams of water dissolve 40.16 grams, at 17° C. 41.7 grams.
