What are the ten uses of chlorine?
Chlorine chemistry helps keep families healthy and improves our environment:
- Water. Chlorine chemistry helps keep drinking water and swimming pools safe.
- Household Disinfectant.
- Food.
- Healthcare.
- Energy and Environment.
- Advanced Technology.
- Building and Construction.

Why chlorine is used in manufacture of pesticides?
In organic chemistry, chlorine is widely used, not only as an oxidizing agent, but as a way of making many useful compounds. For example, chlorine atoms can easily replace hydrogen atoms in organic molecules.
What was chlorine first used for?
First used as a germicide to prevent the spread of “child bed fever” in the maternity wards of Vienna General Hospital in Austria in 1847, chlorine has been one of society’s most potent weapons against a wide array of life-threatening infections, viruses, and bacteria for over 150 years.
What are 3 uses for chlorine?
Chlorine also has a multitude of industrial uses. Including making bulk materials like bleached paper products, plastics such as PVC and the solvents tetrachloromethane, chloroform and dichloromethane. It is also used to make dyes, textiles, medicines, antiseptics, insecticides and paints.
Is chlorine a base or acid?
When chlorine (in any form) is added to water, a weak acid called Hypochlorous acid is produced. It is this acid, not the chlorine, which gives water its ability to oxidize and disinfect. Proper chlorination and filtration give pool water its clear, sparkling appearance. Chlorine exists as a solid, a liquid and a gas.
Does pH lower chlorine?
Extreme pH changes can also affect how the chlorine works in your pool. Chlorine works most efficiently in water with a neutral pH level between 7.4-7.6. If the pool is too alkaline, or more than a pH of 8.0, the efficiency is less than 20 percent.
Does high pH kill chlorine?
With a pH level of 6.0 your chlorine will be highly effective with 97% of your chlorine available to kill bacteria and algae. If the pH is this high it cuts the effectiveness of the chlorine by half or more these pathogens can take much, much longer to kill or inactivate thereby making the pool less safe to swim in.
Can I add pH up and chlorine at the same time?
If both the pH and total alkalinity levels are too high, you’ll need to add pH reducer. Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH.
Should I use chlorine tablets or liquid?
The main benefit offered by liquid chlorine is the ease of addition. However, since liquid chlorine requires more frequent readjustments, has a limited shelf-life, and is required in large volumes, using the tablet chlorine may be a more ideal option for most pool owners.
What is the difference between Clorox and chlorine?
In truth, bleach contains the same base chemical as pool chlorine. That chemical is, of course, chlorine, and the only major difference between the two products is the concentration strength.
Is chlorinating liquid the same as bleach?
Liquid Chlorine and bleach both have the same active ingredient “Sodium Hypochlorite” which makes them the same water purifying compound. The main difference is that bleach is usually a much more diluted form and will require more to be added to the pool for the same effectiveness than if using liquid chlorine.
Which is stronger bleach or chlorine?
Answer: It is true that pool chlorine is stronger than bleach. For bleach and water to be the same strength as pool chlorine and water, you would have to adjust the ratio, increasing the bleach and reducing the water. But no matter which chlorine you use, make sure to test a small area before doing the job.
What happens when you mix bleach and chlorine?
Mixing bleach and acids: When chlorine bleach is mixed with an acid, chlorine gas is produced. Chlorine gas and water combine to make hydrochloric or hypochlorous acids. Hydrochloric acid also causes burns to the skin, eyes, nose, throat, mouth, and lungs.
Does Clorox contain chlorine?
The bleach active in Clorox® Regular Bleach2 is sodium hypochlorite (NaOCl). This is the bleach that people sometimes refer to as “chlorine bleach” (even though the active is hypochlorite, not chlorine). The bleach active in Clorox2® Stain Remover and Color Booster is hydrogen peroxide (H2O2).
What is the difference between bleach and non-chlorine bleach?
What is the difference between chlorine and non-chlorine bleach? These (chlorine) bleaches have sodium hypochlorite as the active ingredient. The non-chlorine or oxygen bleaches like our Clorox2® Stain Remover and Color Booster were developed to be safely used on colored clothing. Some colored items are bleachable.
How do you know if bleach has chlorine in it?
Identification. Non-chlorine bleach always has a label indicating what it is. Some brands that make non-chlorine bleach include Clorox, Seventh Generation and Oxyclean. Clorox also makes one of the most popular chlorine bleaches and it might be easy to get mixed up, so read the labels carefully.
