Pb 2+ ions gain electrons at the cathode and become Pb atoms.Molten lead bromide, PbBr 2 (l), is an electrolyte. negative ions lose electrons at the positively charged anode.positive ions gain electrons from the negatively charged cathode.As a result, they form atoms or molecules of elements : When ions reach an electrode, they gain or lose electrons. Ions move towards their oppositely charged electrode Products of electrolysis Negatively charged ions move towards the anode. The positively charged electrode in electrolysis is called the anode. Positively charged ions move towards the cathode. The negatively charged electrode in electrolysis is called the cathode. The free moving ions in electrolytes are attracted to the oppositely charged electrodes which connect to the dc supply. Under these conditions, the ions in electrolytes are free to move within the liquid or solution.Įlectrolysis is a process in which electrical energy, from a direct current (dc) supply, breaks down electrolytes. in the molten state (heated so they become liquids), or.Electrolysis of molten salts ElectrolytesĮlectrolytes are ionic compounds that are:
