Chlorine is a gas. It does not have a pH value. However, if the chlorine gas is dissolved in water, the following occurs: Cl2 + H2O → HOCl + HCl. hypochlorous acid (HOCl) and hydrochloric acid are formed. Obviously these are acid solutions, and the pH will be below 7.00. The actual figure will depend on the concentrration.

Difference between Chlorine and Chloride | Chlorine vs ...

Chlorine is a naturally occurring element with a symbol Cl and atomic number 17. Under standard conditions, the element is a yellow-green gas. Chloride is an ion of chlorine. Essentially, when atoms gain or lose electrons, they become ions. Chlorine atoms gain one electron to become a chloride ion (Cl−). An ion cannot remain in a free state, and has to combine with another

pH and chlorine values swimming pool - Water quality pool

The pH is a measure of the acidity of the water. The pH scale goes from 0 to 14, where pH 7 is neutral. If the pH is above 7, the water is basic; if it is below 7 the water is acid. The optimum pH for pool water is 7.4, since this is the same as the pH in human eyes and mucous membranes. A pH of 7.4 also gives good chlorine disinfection.

What is Chlorination? — Safe Drinking Water Foundation

When chlorine gas (Cl2) is added to the water (H2O), it hydrolyzes rapidly to produce hypochlorous acid (HOCl) and the hypochlorous acid will then dissociate into hypochlorite ions (OCl-) and hydrogen ions (H+). Cl 2 + H 2 O -> HOCl + H + + OCl-Because hydrogen ions are produced, the water will become more acidic (the pH of the water will decrease). The amount of dissociation depends on the ...
