When the pH is between 5 and 10, the chlorine in the water acts as ___...
Explanation:
pH Range:
- When the pH of water is between 5 and 10, the chlorine in the water acts as a combination of hypochlorous acid and hypochlorite ions.
Role of Hypochlorous Acid (HOCl):
- Hypochlorous acid (HOCl) is a weak acid that acts as a powerful disinfectant and sanitizer.
- It is effective in killing bacteria, viruses, and other harmful microorganisms in water.
Role of Hypochlorite Ions (OCl-):
- Hypochlorite ions (OCl-) are the conjugate base of hypochlorous acid.
- They also contribute to the disinfection process by oxidizing and destroying organic and inorganic contaminants in water.
Equilibrium:
- In the pH range of 5 to 10, there is an equilibrium between hypochlorous acid and hypochlorite ions.
- The proportions of HOCl and OCl- depend on the pH of the water.
Importance of pH Range:
- Maintaining the pH of water within the range of 5 to 10 ensures that the chlorine remains in the form of hypochlorous acid and hypochlorite ions, which are effective disinfectants.
- If the pH strays outside this range, the efficiency of chlorine as a disinfectant may decrease.
In conclusion, in the pH range of 5 to 10, chlorine in water primarily acts as a combination of hypochlorous acid and hypochlorite ions, which help in disinfecting and sanitizing the water effectively.
