Answer: Sum of individual ionic conductances.
- A Zero
- B Sum of individual ionic conductances
- C Concentration times conductance
- D A constant for all electrolytes
Correct answer: B. Sum of individual ionic conductances
Explanation: At infinite dilution ions act independently. ΔM∞ = λ⁺ + λ⁻ (sum of limiting ionic conductances).
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.
