Answer:

Oxidizable Stains and Bleaches

Common examples of oxidizable stains include coffee, lipstick, red wine, and tea

stains [1]. Oxidizable stains go through chemical reactions, specifically oxidationreduction reactions, or redox reactions. An oxidation reaction is the loss of an electron

by a molecule or atom. Simultaneously, a reduction reaction is the gain of an electron

by a molecule or atom.

What causes stains to be oxidizable?

The color in the pigment of the stain is caused when molecules absorb light in

the visible wavelength range (400-780 nm) [10]. The wavelengths that are not absorbed

will be reflected instead and are visible to the human eye. For example, red wine stains

are red because the molecules absorb every wavelength that is not in the red range,

and the red wavelengths (500-600 nm) are then reflected to see.
