the last part in electrochemical series.

but, when conduct the experiment i face a problem.

why the pair of Al/Cu give the smaller reading than Zn/Cu?
i used 2 mol dm^-3 H₂SO₄   as electrolyte in this experiment

thanks

I got the same result too when my students did the experiment.I told them maybe they did'nt clean the metals with sandpaper but the reading was so obvious, it increases once the Al was changed to Zn.

instead of aluminium metal in lab, i also tried the aluminium can  .. but still the small reading of v ;voltmeter.
