Answer: higher reduction potential.
- A lower reduction potential
- B higher reduction potential
- C zero potential always
- D negative potential always
Correct answer: B. higher reduction potential
Explanation: The more positive (higher) the standard reduction potential, the greater the tendency to be reduced.
In a Daniell cell, electrons flow externally from the zinc anode (oxidation) through the voltmeter to the copper cathode (reduction), while the salt bridge completes the circuit.
