Luminescent chemical reaction

 

Materials

luminol, hydrogen peroxide, glowin, coloring substances (eosin, fluorescein, methylene blue), potassium ferricyanide.

 

Experiment

I have 5ml of potassium ferricyanide and 4 drops of hydrogen peroxide in each of the 4 test tubes, and i add in the second tube two drops of eosin, in the third tube two drops of fluorescein and in the last two drops of methylene blue, for finish i add luminol in all of them. This reaction create a glowing light in the tube.

 

How does it work ?

The chemical reaction between hydrogen peroxide and luminol make a source of light, this light emission lasts approximatly 5 sec, but when the chemical reaction is over, the production of light ends.

 

 

Conclusion

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