3 c Aluminium is extracted commercially from an aluminium ore by electrolysis. Cu Cu 2 2e Uses of electrolysis. Water does not carry a charge well so an electrolyte is added to the water.

Thus the strength of the solution remains unchanged. Draw a well labelled diagram for it. C u C u 2 2 e.

For example when a current is passed through molten sodium chloride sodium is deposited at the cathode and chlorine gas is evolved at the anode. Unless electrons make a complete circuit a reaction will not occur. Hello EveryoneDiagram of Electrolysis of Water How To Draw Labelled Diagram of Electrolysis.

CuSO 4 Cu 2 SO 4 2-Copper sulphate Cation Anion. Draw a labelled diagram of the electrolytic cell that can be used to purify copper. Following reactions take place at anode and cathode.

Electrolysis is used in the extraction of metals from their ores. Electrolytic refining The purification uses an electrolyte of copperII sulphate solution impure copper anodes and strips of high purity copper for the cathodes The diagram shows a very simplified view of a cell At the cathode copperII ions are deposited as copper At the anode copper goes into solution as copper. Cations move towards cathode gain electrons and.

At the copper anode copper goes into solution by giving up two electrons. Write the reaction involved. Here is the diagram.

Dilute copper sulphate solution. The products of electrolysing copper sulfate solution with copper electrodes are copper metal and copper ions because the copper anode dissolves. Draw a neat labelled diagram of electrolysis of water.
