What are working electrode and indicator electrode?
Understand the Problem
The question seems to be asking about the concepts of working electrode and indicator electrode in the context of electrochemistry, likely looking for definitions or explanations of their roles in electrochemical cells or experiments.
Answer
A working electrode, or indicator electrode, reveals properties of the analyte solution.
A working electrode, also known as an indicator electrode, reveals the properties of the analyte solution by responding to its activity. It's used in combination with a reference electrode to measure cell potential.

More Information
In an electrochemical system, the working electrode is crucial for analyzing the electrochemical characteristics of solutions by participating in the reaction of interest.
Tips
Confusing the roles of the working/indicator electrode and the reference electrode can lead to errors. Remember, the working electrode responds to the analyte's properties, while the reference electrode provides a stable reference point.
