A lot of things!
As far as pollution goes, I'm not entirely sure.
But here's a list of things that contain chlorine:
Chlorine gas (Cl2)
Table salt (NaCl)
Hydrochloric acid (HCl)
Chlorine dioxide (ClO2)
Refrigerants that contain chlorine are known as chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). Among these, CFC-11 (trichlorofluoromethane) and CFC-12 (dichlorodifluoromethane) are two of the refrigerants that contain the most chlorine.
No, chlorine is an element, consisting only of chlorine atoms. Common table salt contains chlorine in the form of the chloride ion (Cl-)
Household items that may contain chlorine include bleach, cleaning products, pool chemicals, and certain tap water supplies treated with chlorine. It's important to properly store and handle these items to prevent accidental exposure to chlorine gas, which can be harmful if inhaled.
None. distilled water is (theoretically) pure.
Chlorine is not a compound, it is an element. That means that if you have a pure sample of chlorine then it will not contain iodine, or anything other than chlorine. It would be somewhat unlikely to find iodine as an impurity in chlorine, because iodine is solid at room temperature while chlorine is a gas.
Pools use chlorine to keep the water clean.
No, aerosols do not contain chlorine compounds.
No. Both chlorine and hydrogen are elements. Elements cannot contain other elements.
Chlorine is a chemical element and contain only chlorine atoms.
No, not all acids contain chlorine. Acids are compounds that donate hydrogen ions in a solution, and they can contain a variety of elements besides chlorine, such as sulfur, oxygen, or nitrogen. Examples of acids that do not contain chlorine include sulfuric acid (H2SO4) and acetic acid (CH3COOH).
It is possible for still water to contain chlorine if it has been treated with chlorine for disinfection purposes. However, if it is natural still water from a spring or well, it is unlikely to contain chlorine unless it has been contaminated with chlorine from other sources.
Sodium chloride contain sodium and chlorine.
Refrigerants that contain chlorine are known as chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). Among these, CFC-11 (trichlorofluoromethane) and CFC-12 (dichlorodifluoromethane) are two of the refrigerants that contain the most chlorine.
No. Vinegar is a solution of acetic acid, which does not contain chlorine.
Sodium chloride (NaCl) contain chlorine and sodium.
Sodium chloride (NaCl) contain sodium and chlorine.
No, ammonia (NH3) does not contain chlorine. Ammonia is a compound made up of nitrogen and hydrogen atoms. Chlorine is a separate element on the periodic table.
