which of the following is not indicator electrode
Answers
Answer:
Typical indicator electrode designs. Several metals can serve as indicator electrodes for anions that form slightly soluble precipitates with the cation of the metal. A typical example is the use of a silver electrode for indicating chloride ion.

Answer: The indicator electrode is one of two electrodes whose response fluctuates as the analyte changes.
Explanation:
Your question is incomplete as the options are not provided, but most probably the question can be 'What is indicator electrode?'
What exactly is Indicator electrode?
One of the two electrodes whose response varies as the analyte changes is the indicator electrode.
To determine the endpoint of potentiometric titrations, we can use a variety of indicator electrodes.
- a glass electrode
- a metal ion indicator electrode
and so on are further examples. This electrode is known as IE.
The membrane on this electrode responds to analyte activity. As a result, the potential of IE is proportional to the analyte concentration.
The analyte penetrates the electrode membrane at this point, causing a change in membrane potential (this is due to the modification of electrochemical properties).
The other electrode is known as Reference Electrode. The image shows the apparatus showing both the electrodes.
