What is the nominal corrosion potential of zinc?

The nominal corrosion potential of zinc is typically around -1.05V versus a saturated calomel electrode (SCE). This potential indicates how zinc behaves in an electrochemical context, particularly concerning its tendency to corrode when exposed to various environments.

The negative values reflect the electrochemical series, which lists metals based on their electrochemical activity; more negative values signify a higher tendency to oxidize. In the case of zinc, the value -1.05V indicates that it is a more anodic metal compared to materials like aluminum or magnesium, which have higher negative values.

Understanding the corrosion potential is crucial for applications such as cathodic protection, where zinc is often used as a sacrificial anode to protect more noble metals from corrosion. In this context, knowing that zinc has a specific corrosion potential helps in designing systems that effectively manage and predict corrosion risk in structures or components. The other listed values either do not conform to the commonly accepted range for zinc or indicate erroneous representations of its potential.
