Solution
Correct Answer:
Oxidize more readily
- Standard Reduction Potential (E∘): In the standard table, high negative values are at the top (e.g., Li at −3.05 V).
- Stability: A negative E∘ means the reduction process (M++e−→M) is difficult.
- Reactivity: Conversely, the reverse process—oxidation (M→M++e−)—is very easy and energetically favorable.
- Conclusion: Metals high in the series are extremely electropositive and oxidize more readily. They can displace metals below them from their salt solutions.
