Voltage of electrochemical cell

  1. Jan 4, 2012 #1
    hi

    i was wondering if somebody of you knows something about this stuff?

    it is about an electrochemical cell that is made of zinc and copper in sulfuric acid.

    now the reaction is: Zn-> Zn(2+)+2e-
    2H+ + 2e- ->H2
    my problem is, that i do not know whether this cell gives you a voltage that is the potential difference between copper and zinc, cause they are the electrodes or whether it gives you the potential difference between zinc and hydrogen, as this is the reaction that actually takes place?

    sorry about my english, still practising ;-)
