- Ammonium Hydroxide
Properties. Liquid NH 3. Solid NH 3. Two visible states of NH 3. Ammonia is a colourless gas with a characteristically pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules.
By formula: (H 4 N + • H 3 N • 2 H 2 O) + H 3 N = (H 4 N + • 2 H 3 N • 2 H 2 O) Bond type: Hydrogen bond (positive ion to hydride)
The Lewis structure of H 2 O indicates that there are four regions of high electron density around the oxygen atom: two lone pairs and two chemical bonds: We predict that these four regions are arranged in a tetrahedral fashion (Figure \(\PageIndex{6}\)), as indicated in Figure \(\PageIndex{9}\).
Hg 2 Cl 2 + 2 NH 3 → Hg + HgCl(NH 2) + NH 4 + + Cl − Uses Nitric Acid production. The most important single use of ammonia is in the production of nitric acid. A mixture of one part ammonia to nine parts air is passed over a platinum gauze catalyst at 850 °C, whereupon the ammonia is oxidized to nitric oxide. 4 NH 3 + 5 O 2 → 4 NO + 6 H ...
Molecular shape of ammonia. Because, there are three sigma bonds and one lone pair around nitrogen atom, molecular shape of ammonia is trigonal pyramidal.
