The concentration of physiological saline
Disease description:
Recently, I'm looking to buy a low-concentration disinfectant solution for cleaning wounds. Could you please tell me what concentration of saline solution is considered physiological?

Dr. Li Qing
The concentration of physiological saline can be expressed in various ways, such as molarity, specific gravity, milligrams per liter, etc., but the most commonly used method is molarity. Molarity refers to the number of moles of solute per liter of solution, which corresponds to the number of moles of solute particles in one liter of solution. The molarity of physiological saline generally indicates the number of moles of solute per liter of solution and, depending on different experimental requirements, may be 0.9%, 0.45%, 0.2%, 0.1%, etc. For example, 0.9% physiological saline means that there are 9 moles of solute per liter of solution, i.e., the number of moles of solute particles in one liter of solution is 9.
