Luminescent Chemical Reaction


 


 

Materials

 

We use the test tubes, yogurt pots, plastic pipette, graduated cylinder.

For the subtance we use the luminol, the hydrogen peroxide, the glowing, coloring subtances (eosin, fluorescein, methylene blue) and the potassium ferricyanide.

 

Experiment

 

The experiment we're doing is the luminescent chemical reaction.

 

How does it work

 

1.Measure 20ml of potassium ferricianide with a graduated cylinder

2.Pour it in a yogurt pot

3.With a plastic pipette pour 5ml of potassium ferricianide in each of the 4 test tubes.

(use a plastic pipette if you need to)

4.Add two drops of colorant and mix it to make the subtance homogenous.

5.Pour 4 drops of hydrogen peroxide each tube and put the pipette in a yogurt pot. Rinse immediately.

6.Measure 20ml of luminol with a graduated cylinder.

7.Pour the luminol in a yogurt pot.

8.Pour drops of luminol in the test tubes and observe.

 

Conclusion

 

This chemical reaction produces its own light as a consequence it's a primary light source.
