Homework Help: The Galvanic Cell

  1. May 18, 2009 #1
    1. The problem statement, all variables and given/known data
    In a galvanic cell, how do we know which substance is the anode and which is the cathode by using the standard reduction potential chart (redox table)? Ex) Between Cu and Zn, which will donate electrons best...Ex) Pb+2 and Zn+2 which will accept electrons best...I'm really confused...

    2. Relevant equations

    3. The attempt at a solution
    I looked at the values and apparently the higher the E, the more likely reduction will occur but when i compare Cu and Zn don't i have to flip the equation?
