## Question

Zinc but not copper is used for recovery  of Ag From the complex [Ag(CN2)]-  . Why?

Joshi sir comment

Zn is better reducing agent in comparison to Cu for the said complex so it is used

besides it answer by sarika is correct too

zinc is used instead of copper for the said purpose because zinc reacts with faster rate and it also more economical than cu

well the rxn vyl be    Zn + 2[Ag(CN2)-]   => 2 Ag+ [ Zn(CN4)2-]
