A » Free chlorine refers to the amount of chlorine available to disinfect water, while combined chlorine is chlorine that has reacted with organic matter, forming chloramines, which are less effective. Both are measured to assess water quality, as high levels of combined chlorine indicate reduced disinfection efficiency. Maintaining an appropriate balance ensures effective purification and safe water conditions.
