The purpose of the salt water power generation experiment is to produce electricity. According to relevant public information research, salt water power generation experience, required items, stirring rod, copper foil, zinc foil, LED light, quick connector, wire, medicine spoon, salt , cup filled with water. Experimental steps: Use a medicine spoon to put salt into the water and stir continuously with a stirrer until the salt is completely dissolved, then stop stirring. Put the copper foil and zinc foil into the saline solution, then put the copper foil and zinc foil equipped with the LED bulb into the saline solution and observe the phenomenon. Organize experimental materials. Experimental phenomenon, it was found that the LED light turned on. The experimental conclusion is that the salt is sodium chloride, which is the electrolyte. Chlorine atomscontained in the electrolyte gain electrons and react on the copper, causing the generation of bubbles around the copper. Use wires to connect the zinc and copper to form a closed circuit. circuit to form a primary battery.
The methods required to prepare zinc-copper batteries are as follows:
1. First, prepare materials such as copper sheets, zinc sheets, diluted sulfuric. acid, wires, battery cases, etc. Insert copper and zinc foils into diluted sulfuric acid and soak them in the acid.
2. Second, remove the copper foil and zinc foil, wipe the water droplets on the surface with a clean cloth, insert the copper foil and zinc foil into the battery case, and connect the positive and negative . electrodes with wires.
3. Then place the battery case in a container, addingez an appropriate amount of water, soak the battery in water, connect the wires, start a chemical reaction and current will flow out of the copper. sheet to zinc sheet.
4. Finally, observe the reaction of the battery. The generation of bubbles indicates that the battery is fully charged, empty the used liquid and recycle the remaining solution.
