Galvanic Cell Diagram Zinc And Copper. A typical cell might consist of two pieces of metal one zinc and the other copper each immersed each in a solution containing a dissolved salt of the corresponding metal. This arrangement is called a galvanic cell.
Then a zinc electrode is placed in the zinc sulfate solution. Eo red v anode zn zn 2 2 e 1 0 76. A zinc sulfate solution is floated on top of the copper sulfate solution.
In open circuit the voltmeter measures the sum of these two voltages 1 10 v each electrode behaving anodically with respect to its local electrolyte.
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. The electrode potential for copper is 0 34 v and for zinc 0 76 v. The first beaker contains zinc sulfate znso 4 into which a strip of zinc is dipped while the adjacent beaker contains copper sulfate cuso 4 into which a strip of copper is dipped.
