Also know, why does bleach need to be diluted?
Bleach is more effective at killing germs when diluted than when used straight out of the bottle. For most uses, a ratio of nine parts water to one part bleach is recommended. Bleach can expire. Bleach is basically the same as sodium hypochlorite—but not when you calculate dilutions.
Subsequently, question is, what happens if you don't dilute bleach? Avoid using undiluted bleach. Bleach is highly concentrated and is not meant to be used undiluted. Without diluting bleach with water, you'll likely do more damage than good. Bleach is strong enough to still be effective even in a diluted state.

Can you touch diluted bleach?
Both chlorine toxicity and bleach allergies can lead to burns on your skin. Bleach can cause permanent damage to the nerves and tissue in your eyes. But if you come into contact with a large amount of undiluted bleach, or work at a job where you're exposed to bleach often, it's more likely to cause lasting damage.
