5 cards from this section. Quick, good the night before a test.
What is the main difference between galvanic and electrolytic cells?
Think about the direction of energy conversion.
Describe what a redox reaction involves.
Recall OIL RIG: Oxidation Is Loss, Reduction Is Gain.
What is the primary function of a galvanic cell?
Think about which type of cell generates electricity.
True or False: Electrolytic cells can be recharged.
Consider the rechargeable nature of secondary batteries.
A zinc electrode is dipped in a zinc sulfate solution while a copper electrode is in a copper sulfate solution. Calculate the expected cell potential if the standard potentials are +0.34V for copper and -0.76V for zinc.
Remember: The cathode is where reduction takes place.
