ELECTROLYSIS OF DILUTE COPPER SULPHATE COURSEWORK

In the simple electrolysis cell left diagram , the graphite carbon electrodes are, through a large rubber bung, ‘upwardly’ dipped into an solution of dilute copper chloride. The electrode reactions and products of the electrolysis of copper chloride solution are illustrated by the theory diagram above. Electrolysis of copper II sulfate solution and electroplating with other metals e. The extraction of sodium from molten sodium chloride using the ‘Down’s Cell’ Electrolysis always involves a flow of electrons in the external wires and electrodes and a flow of ions in the electrolyte and there is always a reduction at the negative cathode electrode which attracts positive ions, cations and an oxidation at the positive anode electrode which attracts negative ions, anions and it is the ions which are discharged to give the products. This is an oxidation reaction because the chloride ions lose electrons i.

The products of electrolysing copper chloride solution are copper metal and chlorine gas. The platinum or carbon electrodes are inert. Electrolysis of hydrochloric acid 8. In the simple electrolysis cell left diagram , the graphite carbon electrodes are, through a large rubber bung, ‘upwardly’ dipped into an solution of dilute copper chloride. This is an oxidation reaction because the chloride ions lose electrons i.

The purification of zinc by electrolysis Electrolysis of copper chloride is a way of splitting up decomposition of the compound copper chloride using electrical energy. The electrical energy comes sulpyate a d.

The products of electrolysing copper chloride solution are copper metal and chlorine gas. The formation of the products of electrolysing aqueous copper chloride is fully explained with the appropriate electrode equations. The less reactive a metal, the more readily its ion is reduced on the electrode surface.
