Vedclass · Answer

(a) $Cu + 2AgN{O_3} 	o 2Ag + Cu{(N{O_3})_2}$

$Cu + ZnS{O_4} 	o $no reaction

$Cu + FeS{O_4} 	o $no reaction

$\left. {\begin{array}{*{20}{c}}{{E^0}Z{n^{ + 2}}/Zn = - 0.76\,V}\{{E^0}C{u^{2 + }}/Cu = + 0.34\,V}\{{E^0}F{e^{2 + }}/Fe = - 0.40\,V}\{{E^0}A{g^ + }/Ag = + 0.80\,V}\end{array}} ight\}$

As it is clear that reduction potential of copper is more than $Zn $ and $Fe.$  Hence it is unable to displace them from their salts.

Copper displaces which of the metal from their salt solutions
