Description:
Sodium carbonate, Na2CO3, (also known as washing soda, soda ash and soda crystals, and in the monohydrate form as crystal carbonate) is the water-soluble sodium salt of carbonic acid.
It most commonly occurs as a crystalline decahydrate, which readily effloresces to form a white powder, the monohydrate. Pure sodium carbonate is a white, odorless powder that is hygroscopic (absorbs moisture from the air). It has a strongly alkaline taste, and forms a moderatesly basic solution in water.
Application:
It is used as a pH regulator to maintain stable alkaline conditions necessary for the action of the majority of photographic film developing agents. It acts as an alkali because when dissolved in water, it dissociates into the weak acid: carbonic acid and the strong alkali: sodium hydroxide. This gives sodium carbonate in solution the ability to attack metals such as aluminium with the release of hydrogen gas.
It is a common additive in swimming pools used to raise the pH which can be lowered by chlorine tablets aEngineering & Construction Machinery nd other additives which containsCutter & Tongs acids.
In cooking, it is sometimes used in place of sodium hydroxide for lyeing, especially with German pretzels and lye rolls. These dishes are treated with a solution of an alkaline substance to change the pH of the surface of the food and improve browning.
In taxidermy, sodium carbonate added to boiling water will remove flesh from the bones of animal carcasses for trophy mounting or educational display.
In chemistry, it is often used as an electrolyte. Electrolytes are usually salt-based, and sodium carbonate acts as a very good conductor in the process of electrolysis. In addition, unlike chloride ions, which form chlorine gas, carbonate ions are not corrosive to the anodes. It is also used as a primary standard for acid-base titrations because it is solid and air-stable, making it easy to weigh accurately.
1.Soda AshFeatures:
Breaker & Protector True specific gravity 2.533 (20°C), bulk density 0.90min. Easily soluble in water, Maximum solubility at 35.4°C. The aqueous solution appears strong alkalinity. On exposure to air it easily absorbs moisture, carbon dioxide, and gradually forms sodium bicarbonate (caking soda)
2.Soda AshUsage:
1.The manufacture of glass is one of the most important uses of sodium carbonate. When it is combined with silica (SiO2) and calcium carbonate (CaCO3) and heated to very high temperatures, then cooled very rapidly, glass is produced. This type of glass is known as soda lime glass.
2. Soda ash also is used to clean the air and soften water.
3. Manufacture of Caustic Soda and dyestuffs
4. metallurgy (processing of steel and extraction of iron etc),
5. (flat glass, sanitary pottery)
6. national defense (TNT manufacturing, 60% gelatin-type dynamite ) and some other aspects, such as rock oil refining, paper manufacturing, paint, salt refining, softening of hard water, soap, medicine , food and so on.
3.Soda AshApplication:
Soda ash is one of the basic materials for chemical industry, mainly used for metallurgy, glass, textile, dye printing, medicine, synthetic detergent, petroleum and food industry etc.
