(may be broke/outdated!)
i recently constucted an electrolytic cell based on: Zn(s) + Cu +2 —> Zn +2 + Cu(s). the voltmeter read 1 volt, not the expected 1.10 the standard cell potential (Eo). What in the world could account for this?
copper electrode larger than silver one? Zn+2 solution more concentrated? solutions in half-cells have different concentrations? KCl was electrolyte in salt bridge? Zn formed different ions than the copper. like maybe..the Zn+2 electrolyte was Zn(No3)2 and the Cu+2 electrolyte was CuSO4?

likely the missing 0.1 v was across the salt bridge which for whatever reason was not sufficiently conductive
