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.

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.

                                       Luminescent chemical reaction

 

 


 

 

 

 

Materials :  We used potassium ferricyanide, luminol, four test tubes, one plastic pipette, one graduated cylinder and hydrogen peroxide.

 

 

Experiments : For the first test tube, we didn't use colorant. For the 2nd tube, we used eosin. For the 3rd tube, we used fluoroscein and for the last tube, we used methylene blue.

 

 

How does it work ? When we put some drops of luminol in the first tube (without colorant), we obtain a purple color. In the 2nd tube, we put some drops of eosin, we obtain a red color. In the 3rd tube, we put some drops of fluoroscein and we obtain a green color and for the last tube, we put some drops of methylene blue and we obtain a blue color. Depending of the volume of luminol, the light is more or less intense.

 

 

Conclusion :  The luminol is a primary source of light when we put in a recipient potassium ferricyanide and hydrogen peroxide.

Luminescent Chemical Reaction

 

Materials


 We use the test  tubes, Yogurt pots, Plastic pipette, Graduated Cylinder, Luminol, Hydrogen peroxide, Glowing, coloring substances (eosin, fluorescein, methylene blue), potassium ferricyanide and US !!!!!!

 

Experiment

 

 We use four test tubes , we have pour 5 mLs of pottasium ferricyanide in each of the four test tubes, add two drops of colorant and mix it, pour drops of luminol in the test tubes

 

How does it work ?

 

 

The luminol became fluorescent when we have him to overtun into test tubes.

 

Conclusion

 

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

LUMINESCENT CHEMICAL REACTION

 

Materials

For the experiment, we need :

EQUIPMENTS SUBSTANCES
Test tubes Luminol
Yogurt Pots Hydrogen Peroxide
Plastic Pipette

Glowin, coloring substances

(eosin, fluorescein, methylene blue)

Graduated Cylinder Potassium ferricianide
   

 

Experiment

  1. We pour potassium ferricianide in a yogurt pot.
  2. We pour it in four tubes with a plastic pipette.
  3. We add drops of colorant and mix it.
  4. We pour drops of hydrogen peroxide in each tubes and put the pipette in yogurt pot.
  5. We pour luminol in each tubes.

 

How does it work ?

We observed the chimical reaction produce differents glowing coloring light -blue, green, red, white- depending on the colorant. Depending the volume of luminol, the light is more on less intense. The light stays on the surface. When the chemical reaction is over, the production of light ends.

 

Conclusion

Luminol + Hydrogen peroxide = primary source of light
This chemical reaction is primary source of light.

We can see a colored light.

 

How does it work ?

The chemical reaction between hydrogen peroxide and luminol produces colored light. When the chemical reaction is over, the production of light ends.

 

Conclusion

This chemical reaction produces its own light as a con


 

sequence it's a primary light source.

Materials :

-test tubes

-yogurt pots 

-plastic pipette

-graduated cylinder

-luminol

-hydrogen peroxide

-Glowing, coloring substances (Eosin, Fluorescein,methylene blue)

-potassium ferricianide

 

Experiment :

We mix potassium ferricianide and luminol in the first tube ; in the seconde tube we mix potassium ferricianide, luminol and eosin ; we mix, in the third tube, potassium ferricianide, luminol and fluorescein ; and for finish, we mix potassium ferricianide, luminol and methylene blue in the last tube.

 

How does it work ?

When the luminol meets the other substance(s) we see an "explosion" of light.

 

Conclusion :  

There are primary sources of light because they produce their own light.

How does it work ?

 

The mixture between luminol plus hydrogen peroxide plus glowing/coloring substance do an  other colour, but, when the chemical rection is over, the production of light ends.
