How can copper be separated from solution of copper compounds?

Answer 1

Usually in a school experiment, you put copper solution into glass. Then you add Positively and negatively charged sticks which are connected with each other and plugged into electricity, which makes pure copper form on the negatively charged stick.

Answer 2

It is when there is a copper sulphate solution, and the only way to extract the copper is to do electrolysis, as it is more reactive than carbon. In the process, the positive electrode (the anode) is made of the impure copper which is to be purified. The negative electrode (the cathode) is a bar of pure copper. The two electrodes are placed in a solution of Copper Sulphate.Copper ions leave the anode and are attracted to the cathode, where they are deposited as copper atoms. The pure copper cathode increases greatly in size, while the anode dwindles away. The impurities left behind at the anode form a sludge beneath it.

Answer 3

What happens during electrolysis can vary depending on the nature of the electrolyte, its concentration and the material of the electrodes. However, copper ions are very easy to discharge, so usually they are attracted to the cathode where they receive electrons and become copper atoms. For this reason, the cathode becomes plated with solid copper.

Answer 4

One method of extracting copper from a solution of its compounds is electrophoresis. An electrode made of copper would be dipped into the solution. Cu++ ions that are dissolved in the solution would migrate towards the copper electrode and get deposited onto it.

Answer 5

Because the neurons in the sulfate react to the electricity to make copper isolated

Answer 6

In the Daniell cell the electrolyte copper cathode is usually used.
