Passing an electric current through electrolytes causes the ions to move to the electrodes. Positively charged ions move to the negative electrode (the cathode), and negatively charged ions move to the positive electrode (the anode). Ions are discharged at the electrodes producing elements. This process is called electrolysis. When a simple ionic compound is electrolysed in the molten state using inert electrodes, the metal is produced at the cathode and the electrolysis using inert electrodes. Describe how an electric current can pass through an ionic compound. Explain what happens to positive and negative ions during electrolysis and how elements form from their ions. Predict the products of electrolysis of binary ionic compounds in the molten state. WS 1.2 (HT only) half equations for the reactions occurring at the electrodes during electrolysis. Students may be required to complete and balance supplied half equations.
