Answer:C
Which of the following is not the characteristic of a reference electrode?
A. It must have a known output potential B. It must have a constant output potential C. Its output potential is dependent on the composition of the solution D. It is employed in conjunction with the indicator or working electrode
Explanation: The output potential of a reference electrode must be insensitive to the composition of the solution.
