Materialseurope

 

 

 

 

 

 

Test Tubes           Yogurt Pots             Plastic Pipette          Graduated Cylinder

Tube à Essai (x6)

      


Luminol             

Hydogen Peroxide         

Glowing, Coloring Substance (eosin, fluorescein, methylene blue)     

Potassium Ferricyanide

 

 

Experiment :


We measure 20mls of potassium ferricyanide. With a plastique pipette , we pour 5mls of potassium ferrycyanide in each of the 4 test tubes.We add two drops of colorant and we mix it . We pour 4 drops of hydrogen peroxide in each tube . We measure 20mls of luminol. We pour the luminol . Afterwards, we pour dops of luminol and we observe.
