Reduction of Cu+2
You can reduce Cu2+ into Cu(0) via adding of LiBH4 solvent or a water solvent of NaBH4.
Cu2+ Fe(s) → Cu(s) + Fe2
Happens spontaneously due to oxidation potential difference.
Thank you very much. It seems water solution of NaBH4 is suitable for my experiment.
vitamin C may be able to reduce cupric.Try it.
