Reactions
Treatment of sodium azide with strong acids gives hydrazoic acid, which is also extremely toxic:
- H+ + N−
3 → HN3
Aqueous solutions contain minute amounts of hydrogen azide, as described by the following equilibrium:
- N−
3 + H2O HN3 + OH− (K = 10−4.6
)
Sodium azide can be destroyed by treatment with nitrous acid solution:
- 2 NaN3 + 2 HNO2 → 3 N2 + 2 NO + 2 NaOH

Famous quotes containing the word reactions:
“Cuteness in children is totally an adult perspective. The children themselves are unaware that the quality exists, let alone its desirability, until the reactions of grownups inform them.”
—Leontine Young (20th century)
“Separation anxiety is normal part of development, but individual reactions are partly explained by experience, that is, by how frequently children have been left in the care of others.... A mother who is never apart from her young child may be saying to him or her subliminally: “You are only safe when I’m with you.””
—Cathy Rindner Tempelsman (20th century)
“Prolonged, indiscriminate reviewing of books is a quite exceptionally thankless, irritating and exhausting job. It not only involves praising trash but constantly inventing reactions towards books about which one has no spontaneous feeling whatever.”
—George Orwell (1903–1950)
