Some students investigated the electrolysis of silver nitrate solution. Figureshows the apparatus. Notes on how electrolysis works, for ionic compounds in solution and when molten This question is about electrolysis. A student investigates the electrolysis of copper(II) sulfate solution using copper electrodes which do take part in the reaction. When an electric current is passed through a molten ionic compound the compound omposes or breaks down. The process also occurs for electrolysis of: molten lead(II) bromide, concentrated hydrochloric acid, concentrated aqueous sodium chloride, dilute sulfuric acid between inert electrodes (platinum or carbon) Method: Add lead (II) bromide into a crucible and heat so it will turn molten, allowing ions to be free to move and conduct an electric charge. This electrolysis produces silver at the negative electrode. FigureThis is the method usedWeigh the negative electrodeSet up the apparatus shown in FigureSwitch on the power supply Core(a) (i) anode (ii) cathode (b) conducts electricity (c) does not conduct electricity (to operator) plastic is an insulator so operator does not get an electric shock Conduction of electricity requires the presence of MOBILE CHARGED electrolysis of: molten lead(II) bromide, concentrated hydrochloric acid, concentrated aqueous sodium chloride, dilute sulfuric acid between inert electrodes (platinum or carbon) 1 Most experiments involving electrolysis use inert electrodes, which do not take part in the reactions.
