does Mg2+ form complex ions with OH- and NH3? what are we suppose to observe if it did? if it did not?

No, it does not form complex ions in this way. Only a white precipitate of Mg(OH)2 is observed.
If it did form complexes, the white precipitate would re-dissolve if you added excess NaOH or NH3.

a complicated ion is a metallic ion it fairly is bonded to a variety of of Lewis bases that would donate electron pairs to the metallic ion. those bases are called ligands. Examples: CoCl4 2- is the blue indicator that they placed into CaSO4 desiccant. whilst H2O (moisture) replaces the Cl- atoms to style Co(H2O)6 2+ ion, it turns purple so which you already comprehend it's time to alter the desiccant. Cu(NH3)4 2+ is the deep-blue complicated whose color i exploit to verify the small quantity of copper in placed up-1982 pennies. there are thousands of those complicated ions that deliver approximately some very exciting chemistry.
