Will a reaction occur when solid copper (Cu) is added to a solution of iron sulfate (Fe(SO4)) ?Screen Shot 2021-01-20 at 11.03.22 AM-13.png
No Reaction
Yes,
Cu(SO4) and Fe are formed

No reaction.
Copper is less reactive than iron and cannot displace Fe2+ from FeSO4. Using standard potentials:
E°cell = E°(Fe2+/Fe) − E°(Cu2+/Cu) = (−0.44 V) − (+0.34 V) = −0.78 V (non‑spontaneous),
so Cu(s) + Fe2+ → Cu2+ + Fe(s) does not occur.
(For contrast: Cu will reduce Fe3+ to Fe2+, but it will not displace Fe2+.)
