How Does Bleach Work?
Bleach primarily works through a process called oxidation, which breaks down the molecular bonds in pigments and other compounds. This process results in the lightening or whitening of colors. The active ingredient in most bleaches is sodium hypochlorite, which reacts with the pigments in materials to alter their appearance.
When bleach is applied to a surface, it releases oxygen molecules that interact with the pigments. This interaction breaks down the chemical structure of the pigments, effectively making them colorless. The result is a lighter or whitened appearance, depending on the original color and the concentration of bleach used.
