What is Sodium Hypochlorite? Properties and Usage Notes of Sodium Hypochlorite
Tóm tắt nội dung
Sodium hypochlorite is a widely used product in daily life. It is known by various names such as Javel water, Javel bleach, bleaching agent, etc. So what exactly is sodium hypochlorite? What are its properties? What precautions should be taken when using it? Let Loc Thien Chemicals guide you through these details.
What is Sodium Hypochlorite?
Sodium Hypochlorite, or Sodium Hypochlorite, is a chemical compound with the formula NaOCl or NaClO. It is a combination of sodium cation (Na+) and hypochlorite anion (OCl− or ClO−), often regarded as the sodium salt of hypochlorous acid. In solution form, it typically appears as a pale greenish-yellow liquid and is commonly known as bleach or Javel water (Javel).Sodium Hypochlorite can crystallize into NaClO·5H2O, forming a pale greenish-yellow solid that is non-explosive and stable at low temperatures.
Although non-toxic, due to its corrosive properties and byproducts from reactions, it can be hazardous. Commonly used in cleaning and bleaching applications, Sodium Hypochlorite plays a vital role in various industries.
Physical Properties of Sodium Hypochlorite:
- Sodium Hypochlorite typically appears as a pale yellow or chlorine-water-like color, depending on the chlorine concentration in the solution.- Has a strong and rather unpleasant odor, closely associated with chlorine.
- Molar mass: 74.44 g/mol
- Melting point: 18°C
- Boiling point: 101°C
- Specific gravity: 1.20 (relative to water)
- Density: 1.11 g/ml
- Vapor pressure: 2500 Pa at 20°C.
- Soluble in water, forming a solution.
- Sodium Hypochlorite is a strong oxidizing agent used for disinfection and sterilization.

Chemical Properties of Sodium Hypochlorite:
- Sodium Hypochlorite reacts with hydrochloric acid (HCl):
NaClO + 2HCl → NaCl + Cl2 + H2O
- Sodium Hypochlorite reacts with oxalic acid (H2C2O4):
H2C2O4 + NaClO → NaCl + 2CO2 + H2O
- Reaction with sulfuric acid (H2SO4):
H2SO4 + 2NaClO → Na2SO4 + 2HClO
- Sodium Hypochlorite reacts with hydrogen peroxide (H2O2):
2H2O2 + NaClO → NaClO3 + 2H2O
- Reaction with carbon dioxide (CO2) and water:
H2O + NaClO + CO2 → NaHCO3 + HClO
- Reaction with sodium hydroxide solution (NaOH):
NaClO + 2NaOH + 2NH2Cl → 3H2O + N2 + 3NaCl
- Reaction with potassium iodide (KI):
H2O + 2KI + NaClO → I2 + 2KOH + NaCl
- Reaction with buffer solution containing lead sulfide (PbS):
4NaClO + PbS → 4NaCl + PbSO4
- Reaction with highly reactive metals like zinc (Zn) to form metal oxides:
NaClO + Zn → ZnO + NaCl

Precautions when using Sodium Hypochlorite:
- Wear protective gear such as goggles and gloves when handling Javel water to protect your eyes and skin.
- Avoid direct contact with the chemical. In case of contact, rinse immediately.
- Do not mix Sodium Hypochlorite with other chemicals, as it may react exothermically or release toxic fumes, posing hazards.
- Limit the use of Sodium Hypochlorite solution at high concentrations to minimize health risks.
- Work with this solution in a well-ventilated area to reduce the risk of inhaling chlorine gas.
