All about Chlorine: Properties, Color, Uses and more... 2022

Welcome to my Chlorine element data sheet page.

On this page I'll provide comprehensive data for Chlorine. I hope you profit from it.

Chlorine Overview

Name Origin

Greek: chlôros (greenish yellow).

Symbol

Cl (Chlorine)

Description

Greenish-yellow, disagreeable gas. Never found in free form in nature.

Discovery

Discovered By: Carl Wilhelm Scheele
Year: 1774
Location: Sweden

Sources

Salt (sodium chloride, NaCl) is its most common compound. Commercial quantities are produced by electrolysis of aqueous sodium chloride (seawater or brine from salt mines).

Uses

Used in water purification, bleaches, acids and many, many other compounds such as chlorofluorocarbons (CFC).
