Webcomponent of these reagents. Rather than wandering off as solvated cations and acting as uninvolved spectators, the metals, rather than the anion moieties, can initiate and govern the subsequent reactions. To the founders of this field, e. g. Grignard, Ziegler, Gilman, Wittig, and their followers, the metal was critical. WebDue to the presence of solvated electrons (also due to solvated cations), the conductivity decreases as the concentration increases. Evaporation of the ammonia from the blue solutions of alkali metals yields the metal. The blue solutions are moderately stable at room temperature, where ammonia is still a liquid. sva graz kontakt
