Vedclass · Answer

(A) The recovery of $Ag$ from the complex $[Ag(CN)_2]^-$ involves the displacement of $Ag^+$ by a more reactive metal.The standard reduction potentials are $E^o_{Zn^{2+}/Zn} = -0.76 \ V$ and $E^o_{Cu^{2+}/Cu} = +0.34 \ V$.Since $Zn$ has a more negative reduction potential than $Cu$,it is a stronger reducing agent.$Zn$ can displace $Ag$ from $[Ag(CN)_2]^-$ because it can reduce $Ag^+$ to $Ag(s)$,whereas $Cu$ cannot effectively reduce $Ag^+$ in this complex due to its lower reducing power.Thus,both the Assertion and the Reason are correct,and the Reason correctly explains the Assertion.

Assertion : Zinc can be used while copper cannot be used in the recovery of $Ag$ from the complex $[Ag(CN)_2]^-$.
Reason : Zinc is a more powerful reducing agent than copper.
