Hello! Anybody has some idea how could i separate nickel(II) sulfate from copper(II) sulfate with common chemicals and equipment ? I feel like reduction to copper(I) than separation by solubility is the way to go, but i can't think of a practical method.

probably cheaper to buy nickel and copper wire and mix them with sulfurous acid, separation of ions is typically done by chromatography, could also try some sort of precipitation reaction to make copper chloride, nickel chloride solids and use the differences in melting points, which would be the least convienent option.

Ni2+ has a standard reduction potential of -0.26V

Cu2+ is at 0.34V

You can selectively plate either metal onto a variety of metal cathodes using a more reactive metal like iron as an anode... I think. You just dial the cell voltage down until only copper is being reduced.

If I had all those nickels I would put them in a sock and throw them down a hole to prove Gravity is as fast as light
