Description of Sodium Bicarbonate:
Sodium Bicarbonate (NaHCO3), also called baking soda, bicarbonate of soda, or sodium hydrogen carbonate, white crystalline or powdery solid that is a source of carbon dioxide and so is used as an ingredient in baking powders, in effervescent salts and beverages, and as a constituent of dry-chemical fire extinguishers.
Its slight alkalinity makes it useful in treating gastric or urinary hyperacidity and acidosis.
It is also employed in certain industrial processes, as in tanning and the preparation of wool. It is a component of the mineral natron and is found dissolved in many mineral springs. It has the boiling point of 851 degrees Celsius and a melting point of 50 degrees Celsius.
bicarbonate of soda is mainly produced by the Solvay process. Solvay process is the reaction of sodium chloride, ammonia, and carbon dioxide in water.
Calcium carbonate is used as the source of CO2 and the resultant calcium oxide is used to recover the ammonia from the ammonium chloride.
The product shows a low purity (75 %). Pure product is obtained from sodium carbonate, water and carbon dioxide. baking soda can be prepared by carbon dioxide reacts with the sodium hydroxide aqueous solution. This reaction initially produces sodium carbonate.
It is soluble in water and can be separated from water through evaporation.
Uses of Bicarbonate Sodium:
Use of baking soda in the household and the cleaning industry
bicarbonate of soda is one of the best and least expensive cleaning and bleaching agents. You can use it to clean kitchenware, earthenware, a burnt skewer, bathroom tiles or fittings really fast.
Baking soda is perfect at absorbing unpleasant odors and neutralizing dangerous microorganisms. People who promote biological plant cultivation use baking soda as a non-toxic pesticide and fungicide.
Sodium bicarbonate is often used as an active filler in detergents and cleaners to increase pH, which facilitates the washing process.
The cleaning and auto-detailing industries employ preparations with baking soda to remove stubborn stains and damp patches, to whiten upholstery, floor coverings and other surfaces. A mixture of baking soda and water helps remove unpleasant smells in high-traffic bathrooms, basements, dog cages, litter trays, car booths or litter bins.
Sodium bicarbonate in fire-fighting and material processing
We could go on and on about the applications of baking soda! The white, inflammable compound is also used in fire-fighting. It is the main ingredient of fire-extinguishing dry powders and hand-held versatile fire extinguishers designed for fighting different types of fires in homes, offices or vehicles.
Recently, baking soda has drawn the attention of the manufacturers and users of sanders. The loose, whitening sodium bicarbonate is an excellent abrasive for the preservation or removal of the top layer of various materials such as metal or wood.
Medical uses
Can be used to treat heartburn and acid indigestion along with water. Used for treatment in case of an overdose of aspirin. Can be used to get relieved from some insects bites and stings.
It can be used to get relieved from some plants allergy. It is also used to remove splinters from the skin.
Health Information
Health Information Sodium bicarbonate typically found in consumer products may pose a risk of symptoms primarily due to mechanical irritation from sodium bicarbonate particles in the products.
Following good industrial hygiene practices will minimize the likelihood of sodium bicarbonate exposure. baking soda can produce the following adverse health effects:
- Contact – Skin exposures can cause minor skin irritation and itching. Eye exposure to sodium bicarbonate may result in redness, tearing or other irritation.
- Inhalation – The inhalation of sodium bicarbonate dusts can cause nose and throat irritation or coughing.
- Ingestion – The ingestion of sodium bicarbonate may cause gastrointestinal irritation, nausea, vomiting and diarrhea.
- Other Effects – The International Agency for Research on Cancer (IARC) has not classified sodium bicarbonate as a carcinogen (cancer causing).
Proper sodium hydrogen Storage:
Bicarbonate of soda should be stored in a tightly closed container and placed in a cool, dry, well-ventilated area. Keep away from acids, excessive heat and moisture.
Packing of sodium hydrogen:
Packaging Type: In 25kg Bag, or 1mt jumbo bag.
