Q. Copper sulphate solution does not react with

NTA AbhyasNTA Abhyas 2020Electrochemistry

Solution:

$C u S O_{4}$ will react with elements placed above it in electrochemical series and it would not react with elements places below it in electrochemical series.

∴ $C u S O_{4}$ reacts with Zn and Fe placed above it.

$C u S O_{4}$ + Fe → $F e S O_{4} \, $ + Cu

$C u S O_{4}$ + Zn → $Z n S O_{4}$ + Cu

∴ $C u S O_{4}$ does not react with Ag, placed below it.

$C u S O_{4}$ + Ag → no reaction.
