Lumi nescent Chemical Reaction

 

 

Materials :  - test tubes                                    

                  - yogurt pots

                               - plastic pipette

                  - graduated cylinder              

                 

Experiment : -The light emission lasts approximatly 5

                      seconds.

                     -Depending on the volume of luminol, the light

                      produced is more or less intense.

 

How does it work ? In the 4 tubes, there are luminol and

                              hydrogen peroxide and we added in 3

                              tubes differents, eosin, fluorescein and

                              methylene blue.

 

Conclusion : This chemical reaction diffuses another

                    source's light as a consequence it's a secondary

                    light source.
