Chlorine compounds are chemical substances that contain the element chlorine. They can be found in various forms, including gases, liquids, and solids. Common examples include sodium chloride (table salt) and chlorine gas, which is often used for disinfection in water treatment. These compounds play essential roles in industries, agriculture, and household products. Many chlorine compounds are known for their reactivity and ability to form bonds with other elements. Some, like chlorinated hydrocarbons, are used in pesticides and solvents, while others, such as bleach, are used for cleaning and sanitizing. Understanding these compounds is crucial for safety and environmental considerations.
