Redox Reactions And Electrochemistry Ques 139
Question: The reaction $ Z{n^{2+}}+2{e^{-}}\to Zn $ has a standard potential of $ -0.76,V $ . This means [KCET 1992]
Options:
A) $ Zn $ can’t replace hydrogen from acids
B) $ Zn $ is a reducing agent
C) $ Zn $ is a oxidising agent
D) $ Z{n^{2+}} $ is a reducing agent
Show Answer
Answer:
Correct Answer: B
Solution:
Since $ E_{Z{n^{++}}/Zn}^{o} $ is negative, so Zn has greater tendency to be oxidized than hydrogen. Hence it can act as reducing agent.
