Which of the following is strong reducing agent in aqueous solution?
Correct answer: C. Li
- A. Na
- B. K
- C. Li
- D. Ca
Explanation
The correct answer is Li. Lithium is the strongest reducing agent in aqueous solution due to its high hydration energy. Although alkali metals are generally strong reducing agents, lithium's small size allows it to be highly exothermic upon hydration, enhancing its reducing power. Sodium and potassium are also strong reducing agents, but they do not match lithium's effectiveness in aqueous solutions. Calcium, being an alkaline earth metal, is a reducing agent but not as strong as lithium in this context.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
