The most important variable, that is also the most misunderstood, is pH (Hydrogen Potential/Power). What actually is pH? The scientific definition is the logarithm of the reciprocal of the hydrogen ion concentration. Or more simply stated pH is a number between 0 and 14, denoting various degrees of acidity or alkalinity. Neutral water has a pH of 7. Water below 7 is acidic and becomes more acidic as it approached zero. Water above 7 is alkaline and alkalinity increases as it approaches 14. What is the pH of your water and how does it improve or impair the chlorine's ability to be effective? When the pH of your water is 7 or below, chlorine will act primarily as a sanitizer. At this level, it is very effect at killing bacteria. At 7.4, chlorine will act equally as a sanitizer and oxidizer. Above 7.8, the chlorine will act principally as an oxidizer.
The pH of chlorine is 11.7. It would seem logical that adding chlorine into water having a neutral pH would make the water more alkaline and this is true in a majority of the cases. Keeping this in mind, it may be necessary to lower the pH of water with an acid in order to increase the efficacy of chlorine in the killing of bacteria if your water has a high pH to begin with. When chlorine is added to water it becomes hypochlorite ions (OCI) and hypochlorous acid (HOCI) in a quantity determined by the pH as indicated by the chart below: pH OCI HOCI
6.0 3.50% 96.50%
6.5 10.00% 90.00%
7.0 27.50% 72.50%
7.5 50.00% 50.00%
8.0 78.50% 21.50%
8.5 90.00% 10.00%
What else can I help you with?
What is the pH of chlorine?
Chlorine itself does not have a pH since it is a pure element. However, when dissolved in water, chlorine forms hydrochloric acid which can lower the pH of the solution depending on the concentration.
Does chlorine lower PH in waste water?
Yes, chlorine can lower the pH of wastewater because when chlorine is added, it can react with water to form hypochlorous acid, which is acidic. This can cause a decrease in the pH of the water.
Does chlorine lower PH in the pool?
Yes, adding chlorine to a pool can lower the pH level as it increases the acidity of the water. This is because chlorine, in the form of hypochlorous acid, reacts with water to release hydrogen ions, thus lowering the pH. It is important to monitor and adjust both chlorine and pH levels regularly to maintain balanced water conditions in the pool.
How do you raise the chlorine and lower the pH alkalinity in your pool?
To raise chlorine levels, you can add chlorine shock or chlorine tablets to the pool. To lower pH and alkalinity, you can use muriatic acid or pH decreaser. It's important to test the water regularly and make gradual adjustments to avoid overcorrecting levels.
Pool water will not hold chlorine and the pH level is low how can you fix this?
I assume it is an outdoor pool and that you are adding sufficient chlorine. Two reasons why it won't hold chlorine. . . 1. No, or insufficient, conditioner. Sunlight will destroy the chlorine if conditioner is not within 50-80ppm. 2. Phosphates and/or nitrates in the water. Get these checked at your local pool store - or send me a water sample if you can't find anyone to test.E-mail me for address.
What happens to pH when chlorine level is high?
Since most types of chlorine are very high in PH it may effect the over all PH of the water if it is not buffered.
What is the pH of chlorine?
Chlorine itself does not have a pH since it is a pure element. However, when dissolved in water, chlorine forms hydrochloric acid which can lower the pH of the solution depending on the concentration.
Does chlorine raise or lower pH?
depending on the volume of chlorine you put in your pool. Chlorination or simply the adding of chlorine to water is extensively used in many water treatment facilities primarily to disinfect or kill harmful microorganisms, such as bacteria.
How Does chlorine Affect Acidity levels?
Depends on the type of chlorine you are using as each type of chlorine product has it's own pH level. i.e Liquid chlorine (sodium hypochlorite) has a natural pH of about 14. Trichlo products have a pH of about 3 Dichlor products have a pH of about 6.8 Gas Chlorine has a pH of <1 So based on the above lets say you are using liquid chlorine in a concrete pool, the pH will tend to be high (alkaline) due to the high pH of the chlorine product coupled with the fact the pool is concrete.
When opening a pool is it better to the pH or the chlorine right first?
Adjusting the chlorine content will almost certainly affect the pH, so it would be simpler to get the chlorine level correct first and then titrate to the proper pH.
Does chlorine lower PH in waste water?
Yes, chlorine can lower the pH of wastewater because when chlorine is added, it can react with water to form hypochlorous acid, which is acidic. This can cause a decrease in the pH of the water.
Will shocking with chlorine make PH go up?
yes, and the pH can go up significantly depending on what type of chlorine used for shocking. Liquid chlorine (sodium hypochlorite) will cause the PH to increase at a higher rate than that of granular chlorine (such as calcium hypochlorite)
Why is pool Ph low and chlorine high though you have not put chlorine in for weeks?
Low pH in a pool can cause chlorine levels to appear higher due to the pH affecting the effectiveness of the chlorine. The pH imbalance may also be due to factors such as organic debris or algae growth consuming chlorine, leading to a false high reading on the test kit. It is recommended to shock the pool to address any organic contaminants and rebalance the pH to maintain proper water chemistry.
What is the pH of chlorine water?
Chlorinated water is basic: pH = 7-8.
Does chlorine lower PH in the pool?
Yes, adding chlorine to a pool can lower the pH level as it increases the acidity of the water. This is because chlorine, in the form of hypochlorous acid, reacts with water to release hydrogen ions, thus lowering the pH. It is important to monitor and adjust both chlorine and pH levels regularly to maintain balanced water conditions in the pool.

How many electrons dose a chlorine atom have?
The chlorine atom has 17 protons and electrons.
