Method: (copper electrodes) Pour copper sulfate solution into a beaker; Measure and record the mass of a piece of copper foil. Attach it to the negative terminal of a DC supply, and dip the copper foil into the copper sulfate solution Repeat with another piece of copper foil, but this time attach it to the positive terminal Make sure the electrodes do …
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
Clean all equipment after use. ... One method for copper sulfate production is oxidation of metallic copper in diluted sulfuric acid saturated with air through a gas bubbler: 2Cu + O 2 + 2H 2 SO 4 → 2CuSO 4 + 2H 2 O. Only rarely this reaction is used to purify naturally occurring copper. Normally, this method is applied for already remelted ...
Copper sulfate is highly soluble in water, and its solutions are acidic. The compound has a melting point of 110°C for the pentahydrate form and decomposes before boiling.
