THE EFFECT OF CONCENTRATION OF HYDROGEN PEROXIDE (H2O2) AND LUMINOL (C8H7N3O4) ON THE INTENSITY OF CHEMILUMINESCENT GLOW
Chemiluminescence is the study of light emitted after a chemical reaction. In this research two different solutions that produce a chemical reaction, were tested by changing the concentrations of Luminol (C8H7N3O4) and Hydrogen Peroxide (H2O2), each in their respected solution. Solution A was a mixture of Sodium Hydroxide (NaOH) and Luminol (C8H7N3O4), while solution B contained Potassium Ferricyanide K3[Fe(CN)6], and Hydrogen Peroxide (H2O2). The luminescence of mixtures of high, low, and standard values of each solution was measured and analyzed using a two-factor Design of Experiment (DOE). It was hypothesized that the mixture of solutions with the high concentrations of each element would produce the brightest luminescent glow. The hypothesis was accepted, and it was concluded that the solutions containing the higher concentrations of both hydrogen peroxide and luminol produced the brightest luminescent glow.
Glow sticks are advertised to be fun party accessories, but what many do not know is that they can be very vital to everyday safety. Glow sticks are the safest form of light after a natural disaster because they do not require electricity, batteries, or a spark to produce light. Therefore, knowing how to create the brightest chemiluminescent glow is beneficial in producing effective light sticks.Research Done By:
