ELI5: How does bleach work?
gpt
Bleach is NaOCl. The O is oxygen, which is very reactive, meaning it goes around and sticks to stuff and destroys it in the process--it works especially well on organic dyes and stains. When the oxygen in your bleach is all used up, you're left with NaCl, sodium chloride, which is simple table salt.
