Physical and Chemical Properties
Sodium hypo chlorite is a chemical,compound with the formula NaOCl or NaClO, comprising a sodium cation (Na+) and a hypochlorite anion (OCl−or ClO−). It may also be viewed as the sodium salt of hypochlorous,acid. The anhydrous compound is unstable and may decompose explosively.] It can be crystallized as a pentahydrate NaOCl·5H2O, a pale greenish-yellow solid which is not explosive and is stable if kept refrigerated.

Application
- Bleaching,Household bleach is, in general, a solution containing 3-8% sodium hypoc hlorite.
- Cleaning,Sodium hypo chlorite has destaining properties.[35] Among other applications, it can be used to remove mold stains, dental stains caused by fluorosis,and stains on crockery.
- Disinfection, Sodium hypo chlorite in solution exhibits broad spectrum antimicrobial activity and is widely used in healthcare facilities in a variety of settings. It is usually diluted in water depending on its intended use.
- Deodorizing, Sodium hypo chlorite has deodorizing properties, which go hand in hand with its cleaning properties.
- Waste water treatment, Sodium hypo chlorite solutions have been used to treat dilute cyanide waste water, such as electroplating wastes.
Storage
Store in a cool, dry, ventilated storage area with good drainage. Protect from physical damage. Keep out of sunlight, away from direct heat, water and incompatible materials. Do not wash out container and use it for other purposes. Observe all warnings and precautions stated on the container label. Wear personal protective equipment when handling, opening containers and using hypochlorite solution
Contact of sodium hypo chlorite solutions with metals may evolve flammable hydroge n gas. Containers may explode when heated due to release of chlorin e gas.Hypochlorite solutions are corrosive to common container materials such as stainless,steel and aluminium. The few compatible metals include titanium (which however is not compatible with dry chlorin e) and tantalum. Glass containers are safe. Some plastics and rubbers are affected too; safe choices include polyethylene (PE), high density polyethylene (HDPE, PE-HD), (PP), some chlorinated and fluorinated polymers such as polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), and polyvinylidene fluoride (PVDF);as well as ethylene propylen e rubber, and Viton.Containers must allow venting of oxygen produced by decomposition over time, otherwise they may burst.
Sanitation
Calciu m hypochlorite is commonly used to sanitize public swimming pools and disinfect drinking water. Generally the commercial substances are sold with a purity of 65% to 73% with other chemicals present, such as calcium chloride and calcium carbonate, resulting from the manufacturing process. In solution, calciu m hypochlorite could be used as a general purpose sanitizer, but due to calcium residue (making the water harder), sodium hypochlorite (bleach) is usually preferred.
Organic chemistry
Ca lcium hypochlorite is a general oxidizing agent and therefore finds some use in organic chemistry. For instance the compound is used to cleave glycols, α-hydroxy carboxylic acids and keto acids to yield fragmented aldehydes or carboxylic acids. Calcium hyp ochlorite can also be used in the haloform reaction to manufacture chloro form. Calciu m hypochlorite can be used to oxidize thiol and sulfide byproducts in organic synthesis and thereby reduce their odour and make them safe to dispose of. The reagent used in organic chemistry is similar to the sanitizer at ~70% purity.
