The platinum in SHE acts as a:
Correct answer: C. Electrical conductor
- A. Buffer
- B. Salt bridge
- C. Electrical conductor
- D. All of these
Explanation
Pt is a noble metal that is very stable and resistant to corrosion. Because of its stability, like Au, it is often used to make jewelry. As an electrode, it is used to oxidize organics or to generate hydrogen or reduce oxygen.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
