Chlorine is a fundamental industrial chemical derived primarily from sodium chloride (salt) through the chlor-alkali process. It serves as a key raw material in the production of thousands of downstream products used in daily life.

What is Chlorine? Industrial Importance & Properties

Chlorine is a yellow-green gas with a strong, bleach-like odor. It is widely used in chemical manufacturing and industrial processing.

Key Characteristics of Chlorine

· Produced mainly from common salt (NaCl)

· Used in chlor-alkali industrial processes

· Slightly soluble in water

· Denser than air (about 2.5 times heavier)

· Stored as a pressurized amber-colored liquid

When chlorine reacts with water, it forms hydrochloric acid (HCl) and hypochlorous acid (HClO), both important for disinfecting and chemical reactions.
