Chapter 18 Lecture 2 Review from Lecture 1: Electrons move if the Energy is right Move to the more positive potential And They have opportunity Available electrons with empty locations to fill More about Energy: How do you tell which potential of the atoms electron? Construct an E o table: You do about a be-zillion experiment: Define: The electrons in hydrogen to be at zero potential. 2H + + 2e H 2 0.0 Volts To be E o : All solution concentrations are 1M All gas pressures are 1M Convention for constructing cells: Place hydrogen electrode on the left Attach left electrode to the Black Lead on the voltmeter Place test electrode/solution on the right Attach right electrode to the Red Lead on the voltmeter
