Sodium Carbonate serves as a versatile chemical compound used in various industries and laboratory applications. It acts as a cleaning agent, water softener, and pH regulator. In laboratories, Sodium Carbonate plays a crucial role in titration processes, preparing buffer solutions, and creating standard solutions for analytical chemistry. Labtex Bangladesh provides high-quality Sodium Carbonate to meet the needs of both academic and industrial sectors, ensuring accuracy and dependability in every application.

Sodium Carbonate (Na₂CO₃) – Laboratory Grade Chemical for Analytical and Industrial Use

Sodium Carbonate, also known as soda ash or washing soda, is a white, odorless, crystalline powder widely used in laboratories, industries, and educational institutions. Chemically represented as Na₂CO₃, it is an inorganic compound that serves as a versatile reagent for acid-base titration, pH regulation, water softening, glass manufacturing, and various chemical synthesis processes.

At Labtex Bangladesh (Labtexbd.com), we offer high-purity laboratory-grade Sodium Carbonate suitable for chemical experiments, industrial production, and academic demonstrations. Our product meets the quality standards required for accurate and consistent laboratory work.

Chemical Properties of Sodium Carbonate

• Chemical Name: Sodium Carbonate
• Molecular Formula: Na₂CO₃
• Molar Mass: 105.99 g/mol
• Appearance: White crystalline or granular powder
• Solubility: Soluble in water, slightly alkaline in solution
• Melting Point: 851°C
• Density: 2.54 g/cm³
• pH (1% Solution): Around 11

Sodium Carbonate is a strong basic salt, formed from a weak acid (carbonic acid) and a strong base (sodium hydroxide). When dissolved in water, it hydrolyzes slightly, producing an alkaline solution.

Types of Sodium Carbonate

There are mainly three types or forms available, depending on the water content:

1. Sodium Carbonate Anhydrous (Na₂CO₃):

• • Contains no water molecules.
  • Used in analytical chemistry and glass production.

1. Sodium Carbonate Monohydrate (Na₂CO₃·H₂O):

• • Contains one water molecule.
  • Commonly used in laboratories for titration and reagent preparation.

1. Sodium Carbonate Decahydrate (Na₂CO₃·10H₂O):

• • Known as washing soda.
  • Widely used for cleaning, water softening, and industrial processing.

At Labtex Bangladesh, we generally supply the anhydrous or monohydrate forms, depending on laboratory needs and stock availability.

Common Laboratory Uses of Sodium Carbonate

Sodium Carbonate is an essential reagent in most chemistry laboratories. It serves multiple functions across different applications:

1. Acid–Base Titrations:
   It is commonly used as a primary standard for preparing standard alkali solutions due to its high purity and stability.

2. Buffer Preparation:
   Sodium Carbonate helps maintain alkaline pH in buffer solutions for various chemical and biological experiments.

3. Water Softening:
   It reacts with calcium and magnesium ions in hard water to form insoluble precipitates, thus softening the water.

4. Glass and Detergent Manufacturing:
   It lowers the melting point of silica in glassmaking and serves as a builder in detergents.

5. Carbon Dioxide Absorption:
   In analytical setups, it can absorb CO₂ during gas analysis.

6. Cleaning Agent:
   Used for cleaning laboratory glassware and removing acidic residues.

How to Use Sodium Carbonate in the Laboratory

1. Titration:

   • Weigh accurately about 1 g of Sodium Carbonate and dissolve it in distilled water.

   • Dilute to 250 ml to prepare a standard solution.

   • Use it to standardize acids like HCl or H₂SO₄.

2. Buffer Solution Preparation:

   • Mix Sodium Carbonate with its acid salt (sodium bicarbonate) in appropriate ratios to create a buffer near pH 10.

3. Glassware Cleaning:

   • Prepare a 5–10% Sodium Carbonate solution and soak glassware to remove grease and acid traces.

Safety and Handling Precautions

Although Sodium Carbonate is relatively safe, proper laboratory handling is always important:

• Avoid direct contact with eyes and skin — it may cause mild irritation.
• Do not inhale dust. Use it in a well-ventilated area.
• Wear gloves, a mask, and safety goggles.
• Store in an airtight container away from moisture.
• Always label containers properly and keep them out of reach of children.

Refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
