Which of the following metal corrodes the slowest ?A Silver B Iron C Copper D Gold

To determine which metal corrodes the slowest among silver, iron, copper, and gold, we can consider their corrosion potentials. The metal with the lowest corrosion potential is expected to corrode the slowest.

1. Silver: The corrosion potential of silver is relatively low, indicating that it is less likely to corrode quickly.

2. Iron: Iron has a higher corrosion potential compared to silver. This suggests that iron is more prone to corrosion than silver.

3. Copper: Copper has a corrosion potential higher than both silver and iron. This implies that copper is more susceptible to corrosion than both silver and iron.

4. Gold: Gold has the highest corrosion potential among the metals listed. This indicates that gold is the least likely to corrode quickly.

Based on the corrosion potentials, we can conclude that gold corrodes the slowest among silver, iron, copper, and gold.
