Lyrics: a chemistry teacher
Composer: Jay Chou
(metal ion correlation)
Blue flocculent precipitate jumps to the bottom of the test tube.
When copper ion meets hydroxyl group, it will never separate [Cu2++2OH-=Cu(OH)2↓].
When the solution is golden yellow, because iron is trivalent
Light green ferrous iron is fascinating.
(acetylene related)
Calcium carbide sneaks to generate acetylene gas [cac2+2h2o = ca (oh) 2+c2h2].
When ignited, it becomes an acetylene flame with a temperature as high as several thousand.
Evaporating carbon dioxide
Lime water dotted with white sediment [CO2+Ca(OH)2=CaCO3↓+H2O]
(benzene related)
Benzene is not easy to change color when it meets potassium permanganate.
Toluene plus nitro, be careful of TNT.
How beautiful the purple color of iodine molecules in benzene is.
This laid the foundation for extraction.
(electrochemical correlation)
Electrolyte, charged cathode and anode of electrolytic cell
There are high and low prices and electron transfer.
Refining copper, iron, zinc, manganese, nickel, chromium, aluminum, silver and tin.
Leave anode mud
(acid-base correlation)
Colorless phenolphthalein faces alkali and blushes shyly.
When purple litmus meets alkali, cyan gradually fades.
Acid, alkali and salt are dissolved in water and separated by ionization.
Acid and hydroxide metal love triangle
Sodium hydroxide is easy to corrode, deliquescent and astringent.
The common name of caustic soda caustic soda (NaOH) can be seen everywhere.
You are very versatile.
Refining petroleum to make desiccant
(diluted with concentrated sulfuric acid)
Dilute concentrated sulfuric acid and inject acid into water.
Pour slowly along the wall and stir your hands.
Immediately wash the skin with plenty of water and concentrated acid.
Use sodium bicarbonate for emergency treatment.
(Actual output)
Glycerol moistens the skin, making it smooth, delicate and greasy.
Lime slaked lime enters the ground, and the pH value is appropriate.
Look how beautiful the acid red alkali purple test paper is.
There's a smile in your eyes
The following is not available in some versions.
(Related to concentrated hydrochloric acid)
Hydrochloric acid is as transparent as water and sour when stimulated.
The white mist curled up and sent out small drops of water.
Active metals and salts and metal oxides
Think of it as a foreshadowing for me to verify you.
(related to concentrated sulfuric acid)
Sulfuric acid does not want to volatilize, it is sticky and absorbs water.
The stick was picked up, dehydrated and carbonized.
Such as a body discovered by water.
There's a smile in your eyes
Extended data:
The chemical version of blue and white porcelain is a song adapted by a chemistry teacher in Taishan City, Guangdong Province.
social influence
You Yongheng, dean of the School of Education of Sichuan Normal University, believes that this kind of entertaining teaching method is very good and can mobilize the classroom atmosphere. Students can study in a humorous and relaxed environment and remember knowledge more quickly and firmly.
For this video, the vivid language expression makes netizens hooked, especially the students at school, which is even more novel. "Very well, after watching this video, I immediately had the impulse to learn chemistry!" "Why didn't I meet such an excellent chemistry teacher?" "Too talented, this is the real entertaining!" "If I met such a teacher, chemistry wouldn't be so bad!"
