Step1: 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.
Features: The kit is used to prove that the copper chloride solution undergoes chemical changes during electric conduction to form copper and . A necessary accessory while teaching the electrolytic copper chloride solution.
Step2: 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 .
Step3: 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 gas are generated.
Little Tips: Package comes with 1 x Demonstrator and 1 x Users Manual(Chinese). The power supply voltage must not exceed 24 VDC power supply. Before using the instrument, pay attention to fill the solution into the tube, and finally turn on the power. After the experiment is completed, pour out the solution and clean it.
