Question:
In aqueous solutions, the strongest reducing agents in Group 1 and Group 2 elements of the periodic table respectively are
In aqueous solutions, the strongest reducing agents in Group 1 and Group 2 elements of the periodic table respectively are
Show Hint
In aqueous solution, Li (Group 1) and Ba (Group 2) are the strongest reducing agents due to hydration energy and size.
Updated On: May 12, 2025
- Li, Be
- Cs, Ba
- Li, Ba
- Na, Mg
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
- Reducing agent = species that loses electrons easily (oxidized).
- In aqueous medium, Li (Group 1) has the most negative standard electrode potential (–3.04 V) due to high hydration energy.
- In Group 2, Ba is the strongest reducing agent due to its low ionization energy and large atomic size.
- In aqueous medium, Li (Group 1) has the most negative standard electrode potential (–3.04 V) due to high hydration energy.
- In Group 2, Ba is the strongest reducing agent due to its low ionization energy and large atomic size.
