What is chlorines mass number?

Chlorine's mass number is 35.5. This is an average value due to the presence of two isotopes of chlorine, chlorine-35 and chlorine-37, in nature.


What is free chlorine in a pool?

Free Chlorine is the Chlorine which is free to do its work in the pool, as opposed to Combined Chlorine which is chlorine that has combined with contaminants and is tied up and ineffective as a sanitizer in the pool. Sometimes you will see it abbreviated as FAC, which stands for Free Available Chlorine.


What do you do when your total chlorine is high and your free chlorine is low?

Total Chlorine = Free Chlorine + Combined Chlorineor, put another wayTotal Chlorine - Free Chlorine = Combined ChlorineFree Chlorine is the chlorine that is doing its job.Combined Chlorine is the chlorine that has combined with contaminants such as nitrogen. It is ineffective as a sanitizer and it is noxious.Total Chlorine is the total of these two levels.To eliminate the Combined Chlorine (making all the chlorine in the pool Free Chlorine) you must shock the pool to remove the contaminants. You must reach "Breakpoint Chlorination", which is the addition of chlorine to your pool equivalent to the Combined Chlorine level times 10.example:Total Chlorine = 1.5ppmFree Chlorine = 1.0ppmSo, the Combined Chlorine (the difference between the two tests) is .5ppmBreakpoint chlorination, in this example would be .5ppm X 10 = 5ppm. So, in this example, you would add enough chlorine to your pool to raise the chlorine level up by 5 parts per million.


What is the name of the covalent compound ClF3?

ClF5 Is the formula for Chlorine pentaflouride.

Would there ever be a need to add chlorine tablets to a salt water pool?

If the chlorine generator inst run sufficient time or there is a period where an exesive amount of bio material enters the water a litle additional chlorine may at times be an advantage rather then run the filtration equipment longer.


What is the Advantage of Ultraviolet pools?

Water is sterilized as it passes through an ultraviolet light source so few chemicals are needed specifically chlorine.

What are the advantages and disadvantages for alternatives to chlorine for pool maintenance?

The advantage offered by most 'alternatives' is that they, at best, reduce the amount of chlorine you need to add. The only alternative which does the entire job on its own is the Saline (salt) System and although it produces 'chlorine' (from salt dissolved in the pool water) it results in NONE of the obnoxious features attributed to chlorine - no skin irritations, no chlorine odors, no red eyes, no hair damage. A saline pool does not need 'shock' chemicals nor does it require algaecides. Whatever you do, don't get sucked into believing that baquacil is a good alternative.


Is there chlorine in chlorine dioxide?

Chlorine dioxide is a different chemical compound from chlorine. While they both contain the element chlorine, there is no chlorine in the form of Cl2 in chlorine dioxide. Chlorine dioxide (ClO2) is a strong oxidizing agent used for water treatment and disinfection.


What is the name for Cl2 in chemistry?

Cl2 is chlorine. Chlorine exists as a diatomic molecule.

What is the difference between a chlorine atom and a chlorine molecule?

A chlorine atom is a single chlorine atom with the chemical symbol Cl. A chlorine molecule is composed of two chlorine atoms bonded together, forming Cl2. Chlorine atoms are highly reactive, while chlorine molecules are more stable.


Pool chlorine or salt system?

Don't be confused, all a salt system does is perpetually produce chlorine, you still have chlorine in your pool. The advantage is you don't have to go to the pool shop and buy chlorine to add on a regular basis. And if you think about the chlorine level when you, on a weekly basis, add 10L of chlorine. When you do that the chlorine level spikes then fades away until next time. That spike is hard on every part of your pool. With a salt system there is no large spike as it's making little bits of chlorine every few minutes. What you have to be cautious about with a salt system is that it's not maintenance free. You still have to make sure the rest of your water chemistry is on par. AND you can't just put the system on, set it to 100% and walk away. In most cases you can set the system to 20-30% production and that is more then enough!
