One of the commonly used electrode is calomel electrode. Under which of the following categories, calomel electrode comes?
- a
Oxidation-Reduction electrodes
- b
Metal ion-Metal electrodes
- c
Gas-Ion electrodes
- d✓
Metal-Insoluble Salt-Anion electrodes
Metal-Insoluble Salt-Anion electrodes
Strategy: Classify the calomel electrode based on its physical components: a metal, its sparingly soluble salt, and a solution containing the same anion.
Structure of Calomel Electrode: The calomel electrode is represented as .
- Metal:
- Insoluble Salt: (Calomel)
- Anion:
This configuration belongs to the Metal-Insoluble Salt-Anion Electrode category, similar to the silver-silver chloride electrode.
