Whats the definition of chlorine?
Definition of chlorine : a halogen element that is isolated as a heavy greenish-yellow diatomic gas of pungent odor and is used especially as a bleach, oxidizing agent, and disinfectant in water purification — see Chemical Elements Table.
What is chlorine Class 9?
Chlorine is the second lightest halogen and is represented as Cl. The atomic number of this chemical element is 17. It appears as a pale yellow-green gas. Liquid chlorine can cause skin burn and chlorine in its gaseous form irritates the mucous membrane.
What is chlorine and its uses?
Chlorine is used in drinking water and swimming pool water to kill harmful bacteria. It is also as used as part of the sanitation process for industrial waste and sewage. Household chlorine bleach can release chlorine gas if it is mixed with certain other cleaning agents.
What is chlorine made from?
Chlorine can be manufactured by the electrolysis of a sodium chloride solution (brine), which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H2).
How do you write chlorine?
Chlorine is a chemical element with symbol Cl and atomic number 17. Classified as a halogen, Chlorine is a gas at room temperature.
What is the chlorine formula?
Cl2
The chemical formula of chlorine gas is Cl2. It is yellow-green in colour and has an odour which is similar to to the household bleach. It is soluble in water and reacts to form hypochlorous acid and hydrochloric acid.
What are 5 uses of chlorine?

Where is chlorine found?
Occurrence: Found in nature dissolved in salts in seawater and in the deposits of salt mines. Today, most chlorine is produced through the electrolysis of aqueous sodium chloride.
What is the other name for chlorine?
Greenish-yellow gas mistaken for oxygen Davy named it “khloros,” from Greek word for greenish-yellow, and in 1810, he updated the name to “chloric gas,” or “chlorine.”
What is chlorine formula?
The chemical formula of chlorine gas is Cl2. It is yellow-green in colour and has an odour which is similar to to the household bleach. It is soluble in water and reacts to form hypochlorous acid and hydrochloric acid. Chemical formula. Cl2.
What is the pH of chlorine?
Liquid chlorine and bleach (sodium hypochlorite) have a pH of 11.0 to nearly 13.0 so it is logical to think that they will raise the pH of the pool water. The fact is that initially or upon addition liquid chlorine raises pH because sodium hydroxide (lye) is made.
What is chlorine level?
The total chlorine level is the sum of the free chlorine and combined chlorine levels in the pool. For a healthy pool, the free chlorine level should be between 1.0 and 3.0 parts per million (ppm). The Centers for Disease Prevention and Control recommends pH 7.2–7.8 for pools and hot tubs.
What is the best pH for chlorine?
between 7.2 and 7.8
A good chlorine level is between 1.0 and 4.0 parts per million (ppm), while the pH should be between 7.2 and 7.8. Together, they keep bad bacteria at bay: If pH goes up too high, chlorine’s germ-killing power deflates.
What is chlorine and what does it do?
Chlorine is a killer of pathogens by destroying chemical bonds in contaminants. Disinfectants use chlorine compounds in a process that exchanges compounds like atoms. It attacks harmful enzymes in bacteria and viruses. When chlorine confronts enzymes, a chemical reaction occurs. Chlorine replaces hydrogen atoms.
What does the name chlorine mean?

What are the dangers of chlorine?
Chlorine is a strong oxidizing agent and irritant, harmful to eyes and skin, the respiratory passages and lungs. To protect yourself in chlorinated pools, consider wearing a mask and snorkel to shield your eyes, and after swimming, leave the pool area and inhale fresh air to flush the gas out of your system.
What is chlorine commonly used for?
– Maintains salt and water balance – Maintains electrical neutrality in the body (the negative charge of chloride ions balances the positive charge of other ions such as sodium and potassium ions) – Helps fight infections – Helps maintain the pH of the body fluids – Helps maintain blood pressure – Aids digestion
