Using a very simple set up with high school kids,
Zinc Plate
*on*
Filter paper soaked in ZnSO4
*on*
cellophane
*on*
Filter paper soaked in CuSO4
*on*
Copper Plate
*in*
Petri Dish
Copper and zinc plate connected to a speaker. I know the process involved and the equations. Not using a salt bridge. After a while on the base of the Zinc plate there is a build up of a black substance and for the life of me i can't tell what it is.
Any ideas what it is?
