Percipitation of Cu | Bookmark | |||||
How can elemental copper be percipitated out of a CuSO4 solution? If CuSo4 Was used in the cathode compartment of an electrochemical would the copper percipitate as the element once reductoin begun? Can NaBh4 percipitate the Cu Start thinking more like a chemist and less like a criminal |

Some more electronegative metal like Fe or something would push Cu out. For those about to synth,we salute you |

Fe | Bookmark | |||||
They use ferric chloride to etch copper circuit boards, so I don't think iron would work. Electrolysis should work. I tried it with zinc sulfate and it works good. |

Ferric chloride is not Fe.Iron salts do not react with copper. For those about to synth,we salute you |

I'd use aluminum foil in a conc. solution of CuSO4... then soak the ppt with conc. NaOH and finally wash with water. |

>How this Baba wants to precipate copper from coppersulfate by zincsulfate is a riddle for me. He did it he said! What spacetime and universum? You read it wrong. I said electrolysis of copper sulfate to get copper metal should work. I electrolyzed zinc sulfate to get powdered zinc before and it worked with no problems. Obviously English isn't your natural language. Ferric chloride does react with copper. http://www.mgchemicals.com/products/415. |
