Why does it hurt when salt is put on an open wound?

                               Why does it hurt when salt is put on an open wound?

When salt is put on an open wound it hurts or I can say we have a burning sensation. What causes it? The best answer is salt sucks up the moisture around the wound.
Salts are also used as cure for wounds. It hurts because of the heat formed touching our sensitive wound in the salt reaction that kills bacteria.
