Hydrazoic acid, like its fellow mineral acids, is soluble in water. Undiluted hydrazoic acid is dangerously explosive with a standard enthalpy of formation ΔfHo (l, 298K) = +264 kJmol−1. When dilute, the gas and aqueous solutions (<10%) can be safely handled.
Is hydrazoic acid a strong acid?
It does not proceed 100% to products because hydrazoic acid is not a strong acid. Certain salts will also affect the acidity or basicity of aqueous solutions because some of the ions will undergo hydrolysis, just like NH 3 does to make a basic solution.
Is hydrogen azide a strong acid?
Hydrogen azide (or hydrazoic acid) is a volatile compound (m.p. −80 °C, b.p. 37 °C) that is a weak acid having Ka = 1.8 × 10−5.
