"On the Photosensitivity of Hydrogen Peroxide"
Hydrogen peroxide, its properties may involve photosensitivity, which is a chemical doubt and needs to be clarified urgently.
To observe all kinds of chemical substances, whether they are photosensitive or not depends on the structure of their molecules and the characteristics of chemical bonds. Hydrogen peroxide, its molecular formula is $H_ {2} O_ {2} $, and the molecule contains peroxide bonds ($-O - O - $), which are active and unstable.
Taste In the environment of light, light energy can be the source of energy, causing the peroxide bonds in hydrogen peroxide molecules to break. If the bonds are broken, the structure of the molecule changes, triggering a series of chemical reactions. Or decompose to produce water and oxygen, the chemical equation is: $2H_ {2} O_ {2}\ stackrel {light }{=\!=\!=} 2H_ {2} O + O_ {2}\ uparrow $. This change also proves that it responds to light, that is, it has photosensitivity.
However, the sensitivity of light is also affected by various factors. If the concentration of solution, if the concentration of hydrogen peroxide is high, the number of molecules in the unit volume will increase, and the photosensitivity will be more obvious; and if the intensity and wavelength of light, strong light and suitable wavelengths, it is more likely to cause the breakage of peroxygen bonds and exacerbate the change of its photosensitivity.
Furthermore, the characteristics of the medium should not be underestimated. In different solvents or environments, the activity of hydrogen peroxide molecules is different, and its photosensitivity is also different. In some stable media, it may slow down the rate of photoinduced change; in active media, the change of photosensitivity may be faster.
In summary, hydrogen peroxide does have photosensitivity, but the specific performance of its photosensitivity is controlled by various factors such as concentration, light, and medium. In order to know the subtlety of its photosensitivity in detail, repeated experiments are needed to clarify the rules of its change.
