Sodium Hypochlorite

SODIUM HYPOCHLORITE

Sodium Hypochlorite (NaOCl) is a chemical compound commonly known for its use as a bleaching agent and disinfectant. It is most famously recognized as the active ingredient in household bleach. NaOCl is a solution made from reacting chlorine with a sodium hydroxide solution. These two reactants are the major co-products from most chlor-alkali cells. Sodium hypochlorite, commonly referred to as bleach, has a variety of uses and is an excellent disinfectant/antimicrobial agent. Sodium hypochlorite, also known as bleach, bleaching agent, and white spirit, is a chemical compound with the formula NaClO. Sodium hypochlorite is a dilute, yellowish-green solution that is used as a disinfectant and household bleach. The compound is unstable in solution and readily decomposes to release chlorine, its main constituent. In fact, sodium hypochlorite is the oldest and still most important chlorine-containing bleach.

NaOCl is a versatile chemical with a wide range of applications, from household cleaning to industrial processes. However, it must be handled with care due to its corrosive and toxic nature. Proper storage and usage guidelines should always be followed to ensure safety and effectiveness.

WHAT ARE THE USES OF SODIUM HYPOCHLORITE?

Generally, household bleach is a solution containing 2-8% sodium hypochlorite, to which sodium hydroxide is added to slow down the rate of decomposition.
It has stain-removing properties and can be used to remove fungal stains, dental stains caused by fluorosis, and stains on dishes, especially those caused by tannins in tea. It is also used in laundry detergents and as a surface cleaner.
The bleaching, cleaning, deodorizing, and corrosive effects of this compound are due to oxidation and hydrolysis (saponification). Organic contaminants exposed to hypochlorite dissolve in water and become non-volatile, which reduces odor and facilitates their removal.
In solution, bleaching water exhibits a wide range of antimicrobial activity and is used in health and medical facilities. It is dissolved in water at different percentages depending on the type of use.
Strong chlorine solution is a 0.5% hypochlorite solution used to disinfect areas contaminated with body fluids.
Weak chlorine solution is a 0.05% hypochlorite solution used for hand washing, but is typically prepared with calcium hypochlorite granules.
Liquids containing sodium hypochlorite are used as household cleaners and disinfectants, for example, for toilet and bathroom cleaners.
Sodium hypochlorite at concentrations of 0.5% to 5.25% completely destroys pathogenic organisms. At low concentrations, it mainly dissolves necrotic tissue. At higher concentrations, it also dissolves and destroys vital tissue and bacterial species.
Bleach or sodium hypochlorite is used as a bleaching agent in the textile, detergent, and pulp and paper industries. It is also used as an oxidizing agent for organic products.
In the petrochemical industry, (NaOCl) is used in the refining of petroleum products. Large quantities are also used as a disinfectant in water and wastewater treatment and sanitary equipment.
In food processing, bleach is used to disinfect food preparation equipment, in fruit and vegetable processing, mushroom production, beef and poultry production, maple syrup production, and fish processing.

SODIUM HYPOCHLORITE POWDER

Sodium hypochlorite powder is a white powder with a strong chlorine odor, the most widely used type containing 33% chlorine. When used in concentrations between 1% and 3%, this substance has a high disinfectant power that can easily kill harmful microorganisms. This powder is often used for disinfection in order to maintain hygiene and also as a deodorizer in public places. The only problem with this disinfectant powder is that it cannot be stored for a long time because the chlorine in it is lost as a volatile substance, and with the loss of chlorine, the disinfectant property of this substance is also lost.

SOLID SODIUM HYPOCHLORITE

Solid sodium hypochlorite is an unstable chemical compound with explosive potential that decomposes at high temperatures and turns into sodium chlorate and sodium chloride. It is often used as a disinfectant in hospitals and medical facilities and in Dakin’s solution. It is also used in water and wastewater treatment, to remove stains and improve laundry performance. This solid compound is also used as a disinfectant in swimming pools and as a deodorizer and cleaner in detergents and stain removers.

SODIUM HYPOCHLORITE IN DENTISTRY

Sodium hypochlorite is used in dentistry as a 5.25% solution, which is used to clean teeth and rinse gums before fillings. It is also used to disinfect and clean the canals and roots of teeth and to kill harmful bacteria in teeth. This product is marketed in 220 ml and 1 ml sizes, which are only for dental use. Of course, this substance is used in very small quantities because it can cause severe damage to the membranes and tissues of the mouth.

PRODUCTION METHODS OF SODIUM HYPOCHLORITE

NaOCl releases hypochlorous acid (HOCl) when dissolved in water. This acid acts as an oxidizing agent, disrupting cellular functions of microorganisms, leading to their death.

1. REACTING CHLORINE WITH NAOH:

Sodium hypochlorite solution is obtained by passing Cl₂ into a cold and dilute solution of NaOH.

2NaOH (cold and dilute solution) + Cl₂ → NaOCl + NaCl + H₂O

2. BY ELECTROLYSIS OF BRINE SOLUTION:

NaOH and chlorine gas are produced by the electrolysis of brine solution, which is then mixed to form NaOCl.

2Cl⁻ → Cl₂ + 2e⁻
2 H₂O + 2e⁻ → H₂ + 2HO⁻

3. BY OZONE:

Sodium hypochlorite can be obtained by reacting ozone with salt.

NaCl + O₃ → NaClO + O₂

This reaction can happen at room temperature and can be useful for oxidising alcohols.

4. FROM CALCIUM HYPOCHLORITE:

Sodium hypochlorite solution is obtained by reacting sodium carbonate with calcium hypochlorite.

Na₂CO₃ (aq) + Ca(OCl)₂ (aq) → CaCO₃ (s) + 2 NaOCl (aq)

APPLICATIONS OF SODIUM HYPOCHLORITE

NaOCl is used on a large scale. For example in agriculture, chemical industries, paint- and lime industries, food industries, glass industries, paper industries, pharmaceutical industries, synthetics industries and waste disposal industries.

1. HOUSEHOLD BLEACH

Used for whitening clothes and removing stains.
Disinfecting surfaces to kill bacteria and viruses.

2. WATER TREATMENT

Used to disinfect drinking water and swimming pools.
Helps in controlling algae and bacteria in water systems.

3. MEDICAL USES

Employed in wound care to clean and prevent infections.
Used in dentistry as a root canal irrigant.

4. INDUSTRIAL APPLICATIONS

Bleaching of textiles and paper products.
Oxidizing agent in chemical manufacturing.

NaOCl INCOMPATIBILITY CHART

Do NOT mix Sodium Hypochlorite (bleach) with ANY other chemical unless adequate engineering controls and personal protective equipment (PPE) are in place. Accidental mixing may cause dangerous conditions that could result in injury to personnel and/or damage to property or the environment. Common locations where accidental mixing of incompatible chemicals can occur include, but are not limited to, containment systems and drains, sinks, unloading piping and warehouse storage areas.

SODIUM HYPOCHLORITE HAZARDS AND SIDE EFFECTS

Solutions containing more than 500 ppm chlorine are corrosive to some metals, alloys, and many thermoplastics (such as steel resin) and must be removed promptly. Therefore, bleach disinfection is sometimes followed by ethanol disinfection.
Never mix sodium hypochlorite and ammonia because doing so produces a dangerous gas that can potentially cause respiratory problems and suffocation.
Avoid swallowing or contact with eyes or skin because sodium hypochlorite can cause mild to severe irritation, depending on the concentration.
If swallowed, seek medical attention immediately. If the person is conscious, give milk or water, do not induce vomiting, and seek emergency medical attention.
If this chemical comes into contact with skin or eyes, rinse immediately with plenty of water. If you inhale sodium hypochlorite vapors, leave the area and seek fresh air and use an oxygen cylinder.
Interestingly, this substance with strong biocidal effects has limited environmental impacts because the hypochlorite ions are destroyed before they can be absorbed by living organisms.
However, one of the major concerns arising from the use of sodium hypochlorite is its tendency to form persistent organochlorine compounds, including known carcinogens, which can be absorbed by organisms and enter the food chain.
These compounds may be formed during storage and domestic use, as well as during industrial applications. Therefore, regulations must be established for the disposal of this substance worldwide so that it does not affect human health.
