The standard electrode potential of Zn, Ag and Cu are -0.76 , 0.80 and 0.34 volt respectively, then identify the correct statement from following.

Step-by-step solution

Given standard reduction potentials: E^ _ Zn ²⁺/ Zn = -0.76 V E^ _ Cu ²⁺/ Cu = 0.34 V E^ _ Ag ⁺/ Ag = 0.80 V A species with a lower standard reduction potential acts as a stronger reducing agent. Since Zn has the lowest standard reduction potential among the given metals, it has the highest tendency to get oxidized. Therefore, Zn acts as a strong reducing agent and can reduce both Ag ⁺ and Cu ²⁺ ions. Answer: Zn can reduce Ag ^+ and Cu ²⁺
