[edit]DescriptionDSC01962 - Tin reactions.JPG |
English: Chemical reactions of tin chloride. From left to right:
SnCl2 + 2KI -> SnI2(s) + 2KCl (SnI2 should be light yellowish but in this glass there's still some white SnCl2 remaining) SnCl2 + H2S(g) (in surplus) -> SnS(s) (SnS is a brown solid, dissolves in surplus of H2S) SnS + H2S(g) -> [SnS3]2- + H2(g) (a milky stinky liquid remaining) SnCl2 + (NH4)2S -> SnS(s) + H2S(g) (obviously more SnS yield) SnCl2 + H2SO4 -| (nothing as you can see) SnCl2 + 2NaOH -> Sn(OH)2(s) + 2NaCl (this white solid will dissolve in surplus of NaOH or NH3)Deutsch: Chemische Reaktionen mit Zinnchlorid. Von links nach rechts:
SnCl2 + 2KI -> SnI2(s) + 2KCl (SnI2 ist eigentlich hell-gelblich, aber im reagenzglas befindet sich noch ungelöstes weißes SnCl2) SnCl2 + H2S(g) (in surplus) -> SnS(s) (der braune SnS-Niederschlag löst sich in H2S-Überschuss) SnS + H2S(g) -> [SnS3]2- + H2(g) (es verblieb nur eine milchige Flüssigkeit) SnCl2 + (NH4)2S -> SnS(s) + H2S(g) (mehr SnS-Niederschlag) SnCl2 + H2SO4 -| (keinerlei Reaktion) SnCl2 + 2NaOH -> Sn(OH)2(s) + 2NaCl (der weiße Niederschlag löst sich im Überschuss von NaOH oder NH3 zu einem Komplex) |
