In Kammer 1 und 2 einer Reaktionsplatte wurden 2 Kupfer(II)chlorid-Lösung in Reihe geschaltet und zwischen Bleistift-Minen elektrolysiert. Diese elektrolytischen Zellen dient in dem Videoclip als Spannungsquelle zu Elektrolyse von Kaliumiodid-Lösung in Kammer 3.Rötung von Phenolphthalein an der Kathode zeigt Hydoxid-Ionen an, die Braumfärbung um die Anode deutet auf Iod hin.
In well 1 and well 2 of a wellplate6 two copper(II) chloride solutions were electrolyzed between pencil lead electrodes. The result is a copper chlorine battery that powers an electrolysis of an iodide solution and a drop of phenolphtalein indicator in well 3.
Red colour around the negative electrode indicates OH- ions, yellow colour around the positive electrode proves that iodine was formed.

  • @CUBETechie Kupferchlorid ist in wasser gelöst blau. Dieser Blauton bildet sich aber erst nach auflösung des Stoffes in Wasser

  • die blaue lösung kann niemals kupferchlorid sein denn kupferchlorid ist grün soweit ich weis

  • love the birds on the background :)

  • great , but only one note:

    Please for german people please when you post something interesting on the net so please dont make it with deutch language, cuz only you can understand it ! i always noted that every german post it's solution on the net using deutch , so please you language its nly you in the world can understand it, so you cannot think that you will spread it world wide, with all my respects to germany !

  • Its phenolphtalein, an OH- -indicator ;)

  • sprechst du englich? what is the pink stuff
