Why does a wound turn white when you put peroxide on it?
Q: When you put peroxide on a wound, it turns white. Kind of like all the teeny tiny bubbles or something make the wound white for a while. Only where there is exposed tissue it seems. Why does this happen? Thank you.
A: Peroxide is a very active oxidizer, (reacts with oxygen). When you pour it on a wound it reacts with the oxygen in the blood. The bubbling is the oxygen being released. When hemoglobin in blood cells is in the presence of oxygen, like when it’s in your lungs, the hemoglobin absorbs oxygen causing it to turn red. The peroxide removes the oxygen so the hemoglobin no longer has any color, unless you have microscopic vision. It doesn’t take long for any blood cells that are alive to reabsorb oxygen from the air and turn red again. That’s why when you cut yourself the blood is always red. Even if you cut a vein, when the blood gets exposed to the outside air it absorbs oxygen and turns red.
