Question 1.
What does E° represent in electrochemistry?
Show hintHide hint
Consider the reference point used in electrochemistry.
Question 2.
What is the standard reference electrode called?
Show hintHide hint
Think of the electrode assigned as having a potential of 0.00 V.
3Question 3.
What is the standard electrode potential of the Standard Hydrogen Electrode?
- 0.76 V
- 0.34 V
- 0.00 V
Show hintHide hint
It acts as the baseline for measuring other electrodes.
4Question 4.
True or False: A positive E°_cell indicates a non-spontaneous reaction.
- True
- False
Show hintHide hint
Think about what happens in spontaneous reactions.
Question 5.
Calculate the standard cell potential for a galvanic cell involving Ni²⁺/Ni (-0.25 V) and Ag⁺/Ag (+0.80 V). Determine if the reaction is spontaneous.
Show hintHide hint
Remember that spontaneous reactions have positive E°_cell.
Question 6.
Explain how you can determine which metal will undergo oxidation when looking at the table of standard electrode potentials.
Show hintHide hint
Think about the tendency of elements to lose electrons.
