Difference between Chlorine and Chloride

Ever heard of chlorine and chloride? They may sound the same, but they are two very different chemicals. Chlorine is a gas that is often used to disinfect swimming pools, while chloride is a salt form of chlorine. In this blog post, we will explore the difference between chlorine and chloride in more detail. We will also discuss some of the benefits and drawbacks of each chemical. Are you ready to learn more? Let’s get started!

What is Chlorine?

Chlorine is a chemical element with the symbol Cl and atomic number 17. Chlorine is a halogen, found in the periodic table in group 17. Chlorine atoms have 17 electrons around the nucleus, and these fill up the s and p orbitals. Chlorine is a greenish-yellow gas at room temperature, and it is highly reactive, forming compounds with almost all other elements.

Chlorine is used in many industries, such as in the production of paper and cloth, in the treatment of water and sewage, and in the bleaching of wood pulp. Chlorine is also used as a disinfectant. When swallowed, chlorine can be lethal; however, when inhaled in small quantities, it can be therapeutic. Chlorine is found naturally in rocks, soil, and water.

What is Chloride?

Chloride is a chemical compound that is found in a wide variety of materials, including table salt and seawater. It is also a key ingredient in many industrial and household chemicals, such as bleach and hydrochloric acid. Chloride ions are highly reactive, and they are often used as a disinfectant or sanitizer. In addition, chloride plays an important role in the body’s metabolism, helping to regulate blood pressure and fluid balance. Chloride is also essential for the proper function of the nervous system.

Difference between Chlorine and Chloride

Chlorine is a gas at room temperature, while chloride is solid. Chlorine is produced by electrolysis of sodium chloride, while chloride is obtained from the reactions of hydrochloric acid with other metals. Chlorine has a bleaching action, while chloride does not. Chloride is used in the manufacture of PVC and other plastics, while chlorine is used in the production of chlorofluorocarbons (CFCs). Chlorine is toxic to humans, while chloride is not.


Chlorine and chloride are both important elements in water treatment, but they have different purposes. Chlorine is used to kill bacteria and other organisms in the water, while chloride helps to maintain the pH balance of the water. Understanding the difference between these two elements can help you make better decisions about your water treatment system.
