H.ow to grow liquid flowers using sodium and alcohol? This is an impressive experiment shows how to grow a real chemical garden from "sodium flowers".
Reagents and equipment
1. Phenolphthalein
2. metallic sodium
3. Ethanol
4. Isopropanol
5. Bromothymol blue
6. Glass bowl
7. Beaker
8. Glass rod
Procedure
1.Add isopropanol and ethanol into a beaker and stir the solution well.
2.Pour the phenolphthalien and bromothymol blue indicators into the solution.
3.Pour the resulting indicator mixture into a glass bowl.
4.Add a few pieces of metallic sodium,which is a soft metal can even be cut with a knife. Watch as blue-red patterns that look like flowers that appear on the surface of the solution
Process
The sodium reacts with alcohols with the formation of sodium alkoxides,the solution of which have an alkaline nature.The indicators react to change in acidity,and turn the mixture blue,and crimson. Bromothymol turns blue and phenolphthalien turns crimson. As isopropanol has a quiet high viscosity,the slow diffusion of the alkali takes place,an interesting effect which causes a flower to appear! The cunvection in the solution causes these beautiful flowers to grow!
