A zinc sulfate solution is floated on top of the copper sulfate solution then a zinc electrode is placed in the zinc sulfate solution. Connecting the copper electrode to the zinc electrode allows an electric current to flow. This is an example of a cell without a salt bridge, and ions may flow across the interface between the two solutions.

Recycling ZINC Sustainability

Recycling ZINC Sustainability

Zinc metal uses, such as galvanized steel and zinc sheet, are known for their durability. Zinc metals are recycled with high collection and EoL recycling rates. When zinc is used as fertilizer it moves from the technical into the biological cycle and returns to nature. This circular economy contributes to the UN SDGs 9, 11, and 13.
