BASIC CHEMISTRY - Group 2 (Colored Oil Lamp)

Hi, Everyone!
We are from group 2 chemistry class B at University of Jakarta 2021 with our lecturer is Mrs. Irma Ratna Kartika, M.Sc., Tech

Have you ever seen colored oil lamps? Or just hear it?
If you have already, then, what is a colored oil lamp?
A colored oil lamp is a mix of acid, base, sodium bicarbonate, and food dye merged separately.

Science concepts: metathesis reaction, density, sodium bicarbonate, and weak acid.

What is in the solution?
-citric acid/acetic acid
-oil
-baking soda
-food coloring


What is happening?
after experimenting, the reaction that occurs is a gas formation reaction, where the gas formed is carbon dioxide and if we compare the differences between the two lamps, it can be concluded that in colored lamps using vinegar, the bubbles produced are larger and denser. a little, while the bubbles produced by a lamp using citric acid are very small and appear a lot on the rim of the bottle. In addition, in this experiment, the position remained above the acid and baking soda solution. This is because the density of the oil is the smallest among all.

Enjoy watching the video!
Thank you..
