Answer: the quantity of charge.
- A the applied voltage
- B the quantity of charge
- C the circuit resistance
- D the solution temperature
Correct answer: B. the quantity of charge
Explanation: Faraday’s first law: mass deposited ∝ quantity of electric charge (Q = It) passed through the cell.
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.
