Galvanic Cell Concepts and Calculations

This video tutorial by Jeremy Krug explores galvanic cells, focusing on electrode roles, activity series, and standard reduction potentials. It explains how to calculate cell potential and provides examples to determine anode and cathode. Advanced examples include predicting Delta G and designing a cell for maximum potential difference.

What is the role of the anode in a galvanic cell?

• It is where oxidation takes place.

• It is where electrons are gained.

• It is where ions are reduced.

• It is where reduction takes place.

Which metal is more easily oxidized according to the activity series?

• Iron

• Copper

• Silver

• Zinc

What does a higher reduction potential indicate about a metal ion?

• It is less reactive.

• It is more easily oxidized.

• It is more easily reduced.

• It is less easily reduced.

How do you calculate the overall cell potential (E cell) for a galvanic cell?

• Multiply the potentials of the anode and cathode.

• Subtract the potential of the anode from the potential of the cathode.

• Divide the potential of the cathode by the potential of the anode.

• Add the potentials of the anode and cathode.

In a galvanic cell, which position should the cathode be placed in to get a positive E cell?

• First position

• Second position

• Fourth position

• Third position

What is the overall cell potential if the cathode potential is 0.34V and the anode potential is -0.44V?

• 0.78V

• 1.00V

• 0.90V

• 0.10V

What happens to the mass of the cathode in a galvanic cell as the reaction proceeds?

• It remains the same.

• It decreases.

• It fluctuates.

• It increases.

If the overall cell potential is 2.12V and the cathode potential is 0.25V, what is the anode potential?

• -1.87V

• -2.37V

• -1.12V

• -2.12V

Which combination of metals will create the highest potential difference in a galvanic cell?

• Nickel and Copper

• Silver and Zinc

• Copper and Aluminum

• Nickel and Aluminum

What is the overall balanced equation for a galvanic cell with copper as the cathode and aluminum as the anode?

• Cu^2+ + Al -> Cu + Al^3+

• Cu + Al^3+ -> Cu^2+ + Al

• Cu^2+ + Al^3+ -> Cu + Al

• Cu + Al -> Cu^2+ + Al^3+
