Redox Reactions And Electrochemistry Ques 171
Question: Standard reduction potentials at $ 25^{o}C $ of $ L{i^{+}}|Li,,B{a^{2+}}|,Ba,,N{a^{+}}|,Na $ and $ M{g^{2+}}|Mg $ are $ -3.05,,-2.90,,-2.71 $ and $ -2.37 $ volt respectively. Which one of the following is the strongest oxidising agent [CBSE PMT 1994; JIPMER 2002]
Options:
A) $ N{a^{+}} $
B) $ L{i^{+}} $
C) $ B{a^{2+}} $
D) $ M{g^{2+}} $
Show Answer
Answer:
Correct Answer: D
Solution:
The oxidizing character i.e. acceptance of electrons increases with the reduction potential.
