Pelle skall visa sina klasskompisar ett elektrokemi experiment.
Han klipper ut en ”julgran” i bly och stoppar ner den i en bägare med en lösning av
zinknitrat, Zn(NO3)2 (så att hela blygranen täcks av lösningen).
Pelle väntar och väntar men det händer ingenting…
Förklara för Pelle varför det inte blir någon reaktion i bägaren.
Hur skall Pelle göra för att det skall bli någon reaktion? Motivera och skriv
reaktionsformler.
