NEET 2022 Chemistry question
At 298 K, the standard electrode potentials of Cu/Cu, Zn/Zn, Fe/Fe and Ag/Ag are 0.34 V, V, V and 0.80 V, respectively. On the basis of standard electrode potential, predict which of the following reaction can not occur?
Answer: (A)
Solution
Ag is a weaker reducing agent than Cu (), so Ag cannot reduce Cu.
