Zur Darstellung von reinem Zinkchlo

Zur Darstellung von reinem Zinkchlorid setzt man Zink mit Salzsäure um, wobei das Metall zuletzt im Überschuss vorhanden sein muss, behandelt die Lösung mit Chlor, um Verunreinigungen von Eisen in Eisen(III)-chlorid (FeCl3) umzuwandeln, fällt dann das Eisenhydroxid durch Digerieren mit Zinkoxid, filtriert und verdampft, bis ein Tropfen auf einer kalten Porzellanplatte erstarrt.

結果 (英文) 1:

It sets to zinc to represent pure zinc chloride with hydrochloric acid, where the metal last must exist in excess, treated with chlorine solution to convert the impurities of iron to iron(iii) chloride (FeCl3), then drops the iron hydroxide by reheating with zinc oxide, filtered and evaporated, until a drop on a cold porcelain plate solidified.

結果 (英文) 2:

For the preparation of pure zinc chloride is given to zinc with hydrochloric acid to which the metal must be present in excess last, the solution is treated with chlorine to convert impurities of iron in iron (III) chloride (FeCl3), then the iron hydroxide precipitated by digesting with zinc oxide, filtered and evaporated until a drop solidified on a cold porcelain plate.

結果 (英文) 3:

the presentation of pure zinc chloride, zinc with hydrochloric acid, and the metal was in surplus must be present with the solution with chlorine to impurities of iron in iron (iii) chloride (fecl3) transform is then the hydroxide by digestion with zinc oxide, filtered and evaporated until a drop on a cold porzellanplatte solidified.
