Redox Reactions And Electrochemistry Ques 14

Question: If the half-cell reaction $ A+{e^{-}}\to ,{A^{-}} $ has a large negative reduction potential, it follows that [MNR 1992; UPSEAT 2000, 02]

Options:

A) $ A $ is readily reduced

B) $ A $ is readily oxidised

C) $ {A^{-}} $ is readily reduced

D) $ {A^{-}} $ is readily oxidized

Show Answer

Answer:

Correct Answer: D

Solution:

Since $ E_{A/{A^{-}}}^{o} $ has large negative value, the tendency of A to be reduced to $ {A^{-}} $ is very small. In other words tendency of $ {A^{-}} $ to be oxidized to A is very large.
