Chemistry is very interesting, and this science can explain the various phenomena that occur around you. The reason why many people like chemistry is because some chemical reactions produce incredible visual effects.
1.Magical oscillation reaction
This reaction is also known as the “oscillation clock”, in which the Briggs-Rauscher reaction is one of the most common chemical oscillation reactions. In this reaction, the three colorless chemicals involved were acidified potassium iodate (KIO3 + H2SO4), malonic acid and manganese sulfate monohydrate (HOOCCH2COOH + MnSO4·H2O), diluted hydrogen peroxide. (H2O2).
As a result, the color of the solution continues to oscillate between colorless, amber, and dark blue for about 3 to 4 minutes.
2. Kaleidoscope reaction
The beauty of this reaction is that it was accidentally discovered. When the chemist Boris Belousov tried to establish a chemical model of the oxidation of organic molecules in living cells, he observed that the reaction did not proceed to complete, but oscillated between different colors, it seems Like a kaleidoscope.
3. Artificial snow reaction
Sodium polyacrylate is an interesting polymer that has excellent water absorption and water retention capabilities. Therefore, when water is added to the crosslinked polymer, it immediately combines with water to form white fluffy clusters that do not stick to each other and look like snow.
In a few seconds, sodium polyacrylate can absorb 500 times the original mass in pure water. If you add a little fluorescent dye, the visual effect will become more dreamy when viewed in the dark.
4. Candy blasting reaction
When potassium chlorate reacts with candy or other sugar sources, it produces a violet flame and a lot of heat. This reaction has been used in fireworks for centuries. Sugar contains a lot of energy, and the human body slowly releases this energy by gradually breaking the chemical bonds in the sugar molecules. However, when all the chemical bonds are broken at the same time, a large amount of energy is released in the form of light and heat in a short time.
5. Feather explosion reaction
Nitrogen triiodide (NI3) is an extremely unstable compound that explodes as soon as the feather or mosquito touches it and releases purple smoke (iodine).
The iodine atom is relatively large. When three such large atoms are combined with a small nitrogen atom, there is not enough vibration space, which increases the tension to be released in the molecule.
