Difference between Chloride and Chlorine
Introduction
Chloride and chlorine are two terms that are often confused with each other. While they may sound similar, the two substances have distinct characteristics and uses. In this article, we will explore the difference between chloride and chlorine, their properties, and their applications.
What is Chloride?
Chloride is an anion of chlorine. It is a negatively charged ion that is formed when chlorine gains an electron. Chloride is found in salts, such as sodium chloride (table salt) and potassium chloride. It is also present in the human body as an electrolyte and plays a critical role in maintaining the body’s acid-base balance and fluid balance. Additionally, chloride is commonly used in industries such as food processing, petrochemicals, and water treatment.
What is Chlorine?
Chlorine is a chemical element with the symbol Cl and atomic number 17. It is a highly reactive, yellow-green gas with a pungent odor that is used in the production of a variety of chemicals, including plastics, solvents, and disinfectants. As a disinfectant, chlorine is commonly used to sanitize water in swimming pools, drinking water, and wastewater treatment plants. It also plays a significant role in the production of PVC plastics, such as pipes and vinyl siding.
The Main Differences Between Chloride and Chlorine
The main differences between chloride and chlorine are:
– Chloride is an anion of chlorine, while chlorine is a chemical element.
– Chloride has a negative charge, while chlorine is neutral.
– Chloride is found in salts and is an essential electrolyte in the human body, while chlorine is primarily used in industrial and chemical applications.
– Chloride is less reactive than chlorine and does not have the harsh, pungent odor associated with chlorine.
Conclusion
In summary, chloride and chlorine are two distinct substances with different properties and uses. Chloride is an anion of chlorine and is commonly found in salts and the human body. It plays a vital role in maintaining the body’s fluid and electrolyte balance. On the other hand, chlorine is a highly reactive chemical element that is primarily used in industrial and chemical applications, such as disinfecting water and producing PVC plastics. Knowing the differences between chloride and chlorine is essential in understanding their respective applications and uses.
