These awesome chemical reactions were created by a group of scientists from the University of Science and Technology of China.
The first step in their process was researching and selecting the potential reactions. After finding the chemicals that reacted, they refined their shooting techniques to get the perfect images.
1. Basic copper sulphate precipitate (blue) formed after copper sulphate solution was added to a solution of sodium hydroxide.
2. Wishbone (Torenia fournieri) flower with sodium hydroxide solution dropped on to its petal.
3. Purple cabbage being dipped into hydrochloric acid. The acid solution causes the cabbage to change colour from purple to red.
4. Silver chloride precipitate formed after silver nitrate was added to a solution of sodium chloride.
5. Copper sulphate crystals.
6. Eggshell reacting with hydrochloric acid to produce carbon dioxide bubbles.
7. Cadmium sulphide precipitate (yellow) formed after cadmium nitrate was added to a solution of sodium sulphide.
8. Nickel hydroxide precipitate (green) formed after nickel sulphate was added to a solution of sodium hydroxide.
9. Purple cabbage being dipped into sodium hydroxide solution. The basic solution causes the cabbage to change colour from purple to yellow.
10. Green fluorescent droplets formed by mixing the chemicals inside a fluorescent stick.
11. Ammonium chloride smoke formed from a reaction between hydrogen chloride gas and ammonia gas.
12. Zinc reacting with copper sulphate solution and sulphuric acid. The reaction with copper sulphate forms copper (reddish brown), while the reaction with sulphuric acid forms hydrogen bubbles.
13. Magnesium reacting with acetic acid and generating hydrogen bubbles.
14. Zinc reacting with lead nitrate in a soft gel to form lead crystals.
