Sodium Hypochlorite Handbook
Calcium hypochlorite was the first chlorinating agent used. Chlorine also oxidizes and eliminates organic compounds and converts some soluble metallic impurities into insoluble solids that can be removed by filtration. Chlorine is soluble in water to about 7000 ppm at 68°F. It reacts with water forming hypochlorous acid (HOCl). In

Group 17: General Properties of Halogens - Chemistry
Chlorine - Chlorine has the atomic nuer 17 and the chemical syol Cl. Chlorine was discovered in 1774 by extracting it from hydrochloric acid. In its elemental state, it forms the diatomic molecule Cl 2. Chlorine exhibits multiple oxidation states, such as -1, +1, 3, 5, and 7. At room temperature it appears as a light green gas.
Chlorine | Cl2 - PubChem
Chlorine is a commonly used cleaner and disinfectant. Chlorine is a potent irritant to the eyes, the upper respiratory tract, and lungs. Chronic (long-term) exposure to chlorine gas in workers has resulted in respiratory effects, including eye and throat irritation and airflow obstruction. No information is available on the carcinogenic effects of chlorine in humans from inhalation
Calcium - Element information, properties and uses
Calcium was named after the Latin term calx meaning lime, and is a reactive silvery metallic element found in Group 2 of the periodic table. It was first isolated in 1808 in England when Sir Humphry Davy electrolyzed a mixture of lime and mercuric oxide. Today we obtain calcium through the electrolysis of a fused salt such as calcium chloride.

Chlorine - Element information, properties and uses
Chlorine has two stable isotopes chlorine-35 and chlorine-37with Chlorine-35 accounting for roughly 3 out of every 4 naturally occurring chlorine atoms. Chlorine-36 is also known naturally and is a radioactive isotope with a half life of about 30,000 years.
METHYLENE CHLORIDE (DICHLOROMETHANE)
The carbon-chlorine covalent bond is slightly weaker than a carbon-carbon bond, and the bonds to the other halogens are weaker. The stability may be estimated from the relative acidities of the H-X acids. All the hydrohalic acids are very strong, but with small differences in the direction HCl < HBr < HI, with the exception of HF.
