How can reacting aqueous transition ions with ammonia cause a transition hydroxide precipitate, Ammonia and OH- ions remove _______ from water ligands, forming transition metal __________, reaction of a aqueous copper (II) ions with NaOH, [ Cu (H2O)6] 2+ (aq) + 2OH- (aq) ---> [ Cu (OH)2 (H2O)4], reaction of a aqueous copper (II) ions with NH3, [ Cu (H2O)6] 2+ (aq) + 2 NH3 (aq) ----> [Cu (OH)2(H2O)4] (, reaction of a aqueous copper (II) ions with EXCESS NH3.
