1、The kit is used to prove that the copper chloride solution undergoes chemical changes during electric conduction to form copper and chlorine. 2、Simple structure, easy to operate and clean. 3、Compact body and easy to carry,suitable for teaching. 4、A necessary accessory while teaching the electrolytic copper chloride solution. 5、All parts are of high quality and long service life. 1 x Demonstrator1 x Users Manual(Chinese) Item Type:Electrolytic Copper Chloride Solution DemonstratorUsage: Inject the copper chloride solution into the U-shaped branch pipe, insert two graphite carbon rods as electrodes, and place the wet potassium iodide starch test paper near the anode carbon rod to check the released gas. Shortly after the power was turned on, a layer of copper was deposited on the carbon rod as the cathode to indicate that copper was deposited. On the anode carbon rod, there is a bubble, and from its odor and its ability to make the wet potassium iodide starch test paper blue, it can be concluded that the gas is chlorine. From this, it can be seen that the copper chloride solution is subjected to a current, and chemical changes occur while conducting electricity, and copper and chlorine gas are generated.
