Chlorine vs. Chloride: Know the Difference
By Shumaila Saeed || Published on January 1, 2024
Chlorine is a chemical element, a gas at room temperature, while chloride is a negatively charged ion formed when chlorine gains an electron.
Key Differences
Chlorine is a yellow-green gas with a pungent odor, commonly used in disinfection and bleach production. Chloride, on the other hand, is an anion, often found in salts like sodium chloride (table salt), essential for human fluid balance.
