- By the reaction of chlorine with the lime milk, in the presence of sodium hydroxide in a multi-step

process, the grout of chlor is made that subsequently by filtration and drying, chlorine granules are


- This substance is anti- bacterial (anti- odor), anti-septic, anti-fungal and bleaching reagent. Due to

volatility of chlor, it should be kept in sealed containers and stored in a dry place away from direct sun

his compound is relatively stable and has greater available chlorine than sodium hypochlorite . It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air.. It has two forms: dry and hydrated.

Calcium hypochlorite is commonly used to sanitize public swimming pools and disinfect drinking water. Generally the commercial substance is sold with a purity of a 68% (with other additives and contaminants varying based upon the product's intended purpose). For instance as a swimming pool chemical it is often mixed with cyanuric acid stabilizers and anti-scaling agents (in order to reduce the loss of chlorine from ultraviolet radiation and to prevent calcium hardening). Calcium hypochlorite is also used in kitchens to disinfect surfaces and equipment.[3] Other common uses include bathroom cleansers, household disinfectant sprays, algaecides, herbicides, and laundry detergents.

Another plus for using calcium hypochlorite to disinfect water for emergency use is that a little goes a very long way. small bag of calcium hypochlorite in granular form typically costs only a few US dollars and can be obtained in any swimming pool supply section of your hardware store or online. This amount will treat up to 10,000 gallons of drinking water, which is enough for a family of four for some six or seven years at a gallon per day per person!
