Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH 3. It is a colourless gas with a characteristic pungent smell. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers.mmonia is miscible with water. In an aqueous solution, it can be expelled by boiling. The aqueous solution of ammonia is basic. The maximum concentration of ammonia in water (a saturated solution) has a density of 0.880 g/cm 3 and is often known as '.880 ammonia'.
AlCl3 dissolves in water to give Al3+(aq) and Cl-(aq), which is ionic behaviour Hydrated AlCl3, Al(H2O)6Cl3, is undoubtedly an ionic solid, containing the Al(H2O)6 3+ cation AlCl3 sublimes at low temperature, giving vapour of composition Al2Cl6, with tetrahedral Al and two bridging Cl.rom the rules, phi=charge on cation/charge on anion where phi is the ionic potential of the cation. Now Al3+ has high +ve charge on it, so it can distort the cl-cation easily, thus inducing covalent character into it. See Wikipedia for more details.
