Natronlauge (NaOH) ergibt mit Zinkc

Natronlauge (NaOH) ergibt mit Zinkchlorid einen gallertartigen Niederschlag von Zinkhydroxid Zn(OH)2, der sich im Überschuss des Fällungsmittels unter Bildung des tetraedischen, komplexen Tetrahydroxidozinkats(II) [Zn(OH)4]2− wieder löst. Mit Ammoniaklösung anstatt Natronlauge löst sich das zunächst entstehende Hydroxid zum Tetramminkomplex.[9]

結果 (英文) 1:

Sodium hydroxide (NaOH) which arises a gelatinous precipitate of zinc hydroxide Zn(OH)2, with zinc chloride in excess of precipitation means with the formation of the tetraedischen complex Tetrahydroxidozinkats(ii) [Zn(OH)4]2− throws again. With ammonia solution instead of sodium hydroxide dissolves the first resulting hydroxide to the Tetramminkomplex. [9]

結果 (英文) 2:

Sodium hydroxide (NaOH) obtained with zinc chloride a gelatinous precipitate of zinc hydroxide Zn (OH) 2, which is in excess of the precipitant to form the tetrahedral complex Tetrahydroxidozinkats (II) [Zn (OH) 4] 2- dissolves again. With ammonia solution instead of sodium hydroxide, the hydroxide initially formed dissolves to tetraammine. [9]

結果 (英文) 3:

sodium hydroxide (naoh) is a gelatinous precipitate of zinc chloride zinkhydroxid zn (oh) 2 in the surplus of the fällungsmittels under formation of the tetraedischen, complex tetrahydroxidozinkats (ii) [zn (oh) 4] 2− again with ammonia solution instead of sodium hydroxide will disappear. if the first and the tetramminkomplex yellow [9].
