Ammonia (NH 3) behaves like a basic oxide when it reacts with water to form a weak alkali, Ammonium Hydroxide (NH 4 OH). This substance ionises as follows in water: NH 4 OH ---- (H 2 O) ----> NH 4 + + OH-Neutral Oxides are either insoluble in water or do not form acids or alkalis when dissolved. Carbon Monoxide (CO), Dinitrogen Oxide (N 2 O) and water are neutral. When an ionic compound like table salt is placed in water, the partially negative oxygen atoms of the water molecules face and surround the sodium cations. As the ions on the surface of the compound are dissolved into the water, layers underneath are exposed and dissolved, until eventually all of the...Water as a Solvent. Water is one of the most common solvents in nature. In the H2O molecule, an oxygen atom shares electrons with two hydrogen atoms. Water loss is continually replaced by the liquids and foods in the diet and from metabolic processes that produce water in the cells of the body.
