Given the following half-equation for what may happen on the surface electroltsis an electrode in electrolysis. This could be written more accurately as an ionic equation: For latest updates see https: Which of the following is the correctly balanced electrode half equation for the anode in the electrolysis of copper II sulfate with copper electrodes?

Overall equation for the electrolysis of aqueous copper chloride: The extraction of sodium from molten sodium chloride using the ‘Down’s Cell’ Have your say about doc b’s website. Copying of website material is NOT permitted. Electrolysis always involves a flow of electrons in the external wires and electrodes and a flow of ions in the courseworm 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.
