Which alkali metal has the highest reducing power?
Options
- ASodium (Na)
- BPotassium (K)
- CLithium (Li)
- DRubidium (Rb)
Correct answer
C. Lithium (Li)
Step-by-step solution
Among the alkali metals, lithium (Li) has the highest reducing power. This is primarily due to its small ion size, which results in the highest hydration enthalpy and the most negative standard electrode potential (E o ) among alkali metals, making it the strongest reducing agent.
