The potential of a single half-cell on its own:
AIs always one
BCannot be measured
CCan be measured
DIs always zero
Answer & Solution
Correct answer: B. Cannot be measured
1. Only a difference between two potentials can be read.
2. One half-cell alone gives no such difference.
3. So its potential cannot be measured by itself.
