The metal must be 99.99% pure to be used in this way. To ensure this level of purity, copper has to be purified by electrolysis after it has been extracted from its ore. An impure sample of copper may be purified by using the sample as the anode in an electrolysis cell with a pure copper cathode and copper(II) sulfate solution as the electrolyte.
Use data from the Data Booklet to explain why nickel can be purified by a similar electrolysis technique to that used for copper, using an impure nickel anode, a pure .
The electrolyte is a solution containing copper ions, such as copper sulphate. The cathode is a strip of pure copper and the anode is a lump of the impure copper. At the anode: Copper atoms from the impure copper dissolve to form copper ions. This causes the anode to decrease in size.
This content was COPIED from BrainMass - View the original, and get the already-completed solution here! The purification of copper by electrolysis involves an anode of impure copper and a cathode of pure copper. During the electrolysis, copper (II) ions leave the anode slab and plate onto the cathode slab. The reaction at the anode is Cu(s) = Cu2+(aq) +2e-
Sep 13, 2016· What happens is, copper ions in the anode are oxidised and turned into copper ions. These then get deposited in the cathode, where they become copper metal. This can result in an almost pure sample of copper. As for extraction, the aluminium industry is one that uses electrolysis extensively.
Mar 30, 2010· Impure metals containing impurities can be purified using electrolysis where the impure metal is used as the anode and a piece of metal is used as the cathode. the electrolyte is a solution containing the ions of the metal to be purified. Purification of copper Pure copper and silver can be obtained through the process of electrolysis.

Chem last lab !! sem 2 !! - . Electrolysis is a process whereby when a solution contains positive and negative ions, it conducts electricity. When electricity passes through a solution, chemical reactions may occur at the electrodes. In this process, the positive electrode (the anode) is made of the impure copper which is to be purified.
Copper refining to an almost pure state done by electrolysis is an excellent example of the process. Blister copper is considered to be a highly pure form of copper - around 99%. However, in today's market, this level of purity is still not enough; as a result, the blister copper is purified further using an electrolysis process known as ...
So he said that those particles were salts and bad impurities which my purifier can not filter out, and his purifier can, thus having few particles in his glass. So my question is, can this method detect the impurities in water, or is it just some dirty sales tactic?
Impure copper is used as the anode while a piece of pure copper is used as the cathode. Pure copper from the impure copper anode will dissolve into the electrolyte, and pure copper is then deposited onto the copper cathode. Impurities are left on the anode, which will then fall off to collect below the anode.
1)Can you explain how copper is purified by electrolysis. You should be able to say which substances are placed at each electrode and how they will change when electricity flows. You should include a description of the electrolyte (solution).
