This is a fun, beautiful and entertaining chemical experiment that can easily be repeated at home. All reagents are in almost every kitchen, and if not, they can be bought at any grocery store. I'll show you how to make a kind of lava lamp, but unlike the real one, it will start working immediately and will not require heat for of the reaction.Then pour the sunflower oil. This is the main component, so we fill in the whole jar.We pour vinegar into a small container.Add food to this amount of vinegardye.Turn on the backlight.And we put a vessel with oil and soda on this highlight. The lava lamp should also be highlighted.Verify the mixing of mixed vinegar with dye.And our lava lamp immediately begins to work. Bubbles alternately fall to the bottom, then rise up to the neck of the can.This entertainment experience can be repeated with children, I am sure that they will be delighted.The principle of operation is simple: vinegar is heavier than oil and therefore the bubbles first sink to the bottom. Touching the bottom, the reaction of acetic acid with soda occurs, resulting in carbon dioxide bubbles, which pull the bubble up. Reaching the top, carbon dioxide comes out and the bubble drops to the bottom again. So the cycle repeats for a certain time, until the reaction of vinegar and soda is completely completed. PS: You can use several dyes at once, mixed in different containers with vinegar. And pour them at the same time. It will look very cool.
It will be required
- Food soda.
- Vinegar table.
- Sunflower oil.
- Food coloring - the color to your taste.
Making a chemical lava lampTake a tablespoon of soda and pour it on the bottom of the jar. It is necessary that the whole bottom is covered with soda.
