What is the principle of salt water car in Baidu?

The main component of salt water is the electrolyte NaCl, which contains a large amount of Na+ and Cl- ions. Under normal circumstances these two ions should be able to move freely in the solution, but in a small car this can happen. be set Some sort of filtering device is installed to facilitate the passage of one of the ions through the filter to the other side; or different metal plates are placed on both sides of the container containing the salt water, which facilitates the passage of Na+; ions accumulate at one end, and Cl- ions are more likely to accumulate at the other end, and the effect is the same.

In this way, on both sides of the filter, or at both ends of the brine container, there will be a potential difference due to the imbalance of positive and negative ions, which is equivalent to connecting a battery. Driven by this battery, the micro DC motor inside the electric carstick turns and drives the wheels. run.

I don't know if this is the case Today, our Chinese teacher gave me a small technology production job. I made a car powered by salt water. Think about it, how can salt water produce electricity? If you want to know, follow me!

In the afternoon, my mother bought me parts for a salt water car. Once I got home, I excitedly started making it. I first broke all the parts with my hands and followed the steps in the instructions to make the salt water car step by step. Its hull is blue and its chassis is all white. It looks like a real racing car, it's really cool! I thought: the time to witness a miracle is coming! I put two drops of salt water on the car's FC module to see if it can drive. As a result, he always stood there motionless. HH? I checked it carefully forsee what the problem was. Oh, I finally discovered that the second stage gears and bearings were not glued together and the FC module was not fully seated. As soon as I fixed these things, the wheel started spinning quickly. I put her down on the floor, and she ran up to the wall with a "chirp", hit the wall, turned around and got back on my feet. I shouted happily: "My experiment was successful, my experiment was successful."

According to the instructions, this is an environmentally friendly fuel - the concept of a salt water car Until now, no such car has been produced in the world, but I believe such a car will exist. in the future, because There is no difficulty in the world that cannot be overcome, and there is no enemy that cannot be defeated. The science turns out to be so amazing! I must study hard in the future, become a scientist and explore the mysteriesof the world.

Objective of the salt water electricity production experiment

1. Preparation materials: copper foil (copper coins can be substituted, such as game machine coins), zinc foil (zinc plated coins can be substituted), paper clips, cooler, and salted water.

2. Assembly: As shown in the picture (note that the two sheets cannot be placed upside down).

3. Finally, connect the first and last pole to the small LED lights with wires. You can see that the little lights will shine. (For 10 grids, the voltage is about 1.5V)

Theoretically, as long as there are enough small grids, the voltage can reach 220V, but it is not recommended to experiment, because the voltage is so high and without corresponding insulation materials and protective measures, it is easy to cause injury.

The purpose ofsalt 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. The chlorine atoms contained inthe electrolyte gains electrons and reacts on the copper, causing bubbles to be generated around the copper. Use wires to connect the zinc and copper to form a closed circuit. circuit to form a primary battery.
