Practice Problem: Galvanic Cells and Reduction Potential

The video tutorial explains the concepts of galvanic cells and reduction potential, focusing on a galvanic cell consisting of gold and nickel half cells. It provides electrochemical data and guides viewers on identifying the cathode and anode. The tutorial also covers calculating the standard cell potential, emphasizing the importance of using standard reduction potentials directly from tables without alteration.

What are the standard reduction potentials for gold and nickel in the given galvanic cell?

• -1.498 V for gold and +0.257 V for nickel

• +1.498 V for gold and -0.257 V for nickel

• +1.498 V for nickel and -0.257 V for gold

• +0.257 V for gold and -1.498 V for nickel

In a galvanic cell, where does the reduction process occur?

• In the salt bridge

• At the anode

• In the electrolyte

• At the cathode

Which half reaction is flipped to represent oxidation in the galvanic cell?

• Gold 3+ oxidation

• Nickel 2+ reduction

• Gold 3+ reduction

• Nickel 2+ oxidation

What is the formula used to calculate the standard cell potential?

• E cell = E cathode - E anode

• E cell = E anode + E cathode

• E cell = E cathode + E anode

• E cell = E anode - E cathode

What is the calculated standard cell potential for the given galvanic cell?

• 0.755 V

• 1.755 V

• 2.755 V

• 1.241 V
