Sodium Hypochlorite is an inorganic chemical with the chemical formula NaClO(or NaOCI). The chemical compound comprises a hypochlorite anion(CIO- or OCI-) and a sodium cation(Na+). Sodium hypochlorite can also be seen as the sodium salt present in hypochlorous acid.

Sodium hypochlorite is an unstable anhydrous compound and is liable to be explosive when decomposed. The chemical is often applied for use as a disinfectant and cleaning agent. The chemical decomposes easily and is very unstable. In this article, we've discussed the top 10 facts you need to know about sodium hypochlorite.

Sodium Hypochlorite Chemical Names

Sodium hypochlorite is also known as bleach, clorox, and sodium oxychloride. It is also known as Dakin's solution when in O.5w/v solution.

Physical Structure

Sodium hypochlorite is often seen as a pale greenish-yellow solid. It has a chlorine-like and sweetish odor. Sodium hypochlorite occurs as a solid and as a liquid once diluted with water.

Reaction With Water

Sodium Hypochlorite reacts with water and decomposes into oxygen and chlorine gasses. Sodium hypochlorite dissolves in water to form two chemicals that help in the process of disinfection and oxidation.

Is Bleach The Same As Sodium Hypochlorite?

Sodium Hypochlorite is a white powder, but when dissolved in water it is more widely used as a bleach. Solutions of sodium hypochlorite are known as bleach, though household bleach is made of several other compounds including calcium hypochlorite and sodium hydroxide.

Is Chlorine The Same As Sodium Hypochlorite?

Chlorine is not the same as sodium hypochlorite. Sodium hypochlorite is an inorganic compound with the chemical formula NaOCI while chlorine is a gas when at room temperature and has the chemical formula Cl2. This is the main difference between them, they are both used as a disinfectant, bleaching agent, etc. In terms of chemical bonding, the difference between sodium hypochlorite and chlorine is that in sodium hypochlorite there's an electrostatic force of attraction between the hypochlorite anion and sodium cation while chlorine has a chemical bond between its chlorine atoms.

Daily Uses

Here are some of the daily applications of Sodium Hypochlorite:


Sodium hypochlorite is known to have destaining abilities. It can be applied for use in the removal of mold stains, crockery stains caused by tea tannins, and dental stains brought by fluorosis. It is also found in laundry detergents and as a surface cleaner.

Its cleaning, caustic effect, bleaching, and deodorizing effects are because of hydrolysis and oxidation. Dirt exposed to sodium hypochlorite becomes non-volatile and water soluble which facilitates the removal and reduction of odor.


Sodium Hypochlorite is one of the main components of household bleach. It contains about 3-8% of sodium hypochlorite by weight and 0.01-0.05 sodium hydroxide. Sodium hydroxide is used in decomposing sodium hypochlorite into sodium chlorate and sodium chloride.

Water Treatment

Sodium hypochlorite chemical solution is applied for use in treating dilute cyanide wastewater. Sodium hypochlorite is used in batch treatment operations to treat highly concentrated cyanide waste, such as the plating solution of silver cyanide.

Sodium hypochlorite is often used in Industries as a biocide for the control of bacteria and slime formation in the water system of paper and pulp mills, power plants, etc., In solutions of about 10-15% weight.

Uses In Textile Industry

Sodium Hypochlorite is used in the textile industry as a bleaching agent. It is used to bleach fabrics and leather. It bleaches the materials and removes any form of impurities and also increases the color brightness. It is also used in providing textiles with a chlorine concentration of about 0.5%.

Packaging Procedures

Flammable hydrogen gas is Likely to evolve from the contact of sodium hydrogen solutions with metallics. Containers containing sodium hypochlorite may explode when chlorine gas is heated.

Sodium hypochlorite solutions are corrosive to some of the common containers such as aluminum and stainless steel. The compatible materials that came to be used in packaging and storing sodium hypochlorite solutions include tantalum and titanium (which is not compatible with dry chlorine). Glass containers can also be used in packaging sodium hypochlorite. Some Rubber and plastics are affected, some safe choices include polypropylene, polyethylene(high density), Viton, and some fluorinated and chlorinated polymers such as polytetrafluoroethylene, and polyvinyl chloride.

The containers that'll be used in packaging sodium hypochlorite must allow the venting of oxygen that's produced through decomposition over time, or else they'll burst.
