${\mathrm{C}\mathrm{u}\mathrm{S}\mathrm{O}}_4$will react with elements placed above it in electrochemical series and it would not react with elements places below it in electrochemical series.

∴${\mathrm{C}\mathrm{u}\mathrm{S}\mathrm{O}}_4$reacts with Zn and Fe placed above it.

${\mathrm{C}\mathrm{u}\mathrm{S}\mathrm{O}}_4$+ Fe →${\mathrm{F}\mathrm{e}\mathrm{S}\mathrm{O}}_4\mathrm{ }$+ Cu

${\mathrm{C}\mathrm{u}\mathrm{S}\mathrm{O}}_4$+ Zn →${\mathrm{Z}\mathrm{n}\mathrm{S}\mathrm{O}}_4$+ Cu

∴${\mathrm{C}\mathrm{u}\mathrm{S}\mathrm{O}}_4$does not react with Ag, placed below it.

${\mathrm{C}\mathrm{u}\mathrm{S}\mathrm{O}}_4$+ Ag → no reaction.
