The correct answer is: B. Stable half cell potential.
A silver chloride electrode is a type of reference electrode that is used in electrochemistry. It is made up of a silver wire that is coated with silver chloride. The electrode is placed in a solution of potassium chloride, which forms a salt bridge with the solution that is being measured. The silver chloride electrode has a stable half cell potential, which means that it does not change significantly over time. This makes it a good choice for use as a reference electrode.
The other options are incorrect because:
- A. Large half cell potential is not a desirable property for a reference electrode. A reference electrode should have a stable half cell potential, so that it can be used to measure the potential of other electrodes accurately.
- C. Stable resting potential is a property of cells, not electrodes. The resting potential of a cell is the voltage difference across the cell membrane when the cell is not active.
- D. Stable action potential is also a property of cells, not electrodes. The action potential is a rapid change in the voltage across the cell membrane that occurs when a cell is activated.
