Sodium carbonate - Import export

Soda Ash Dense or Sodium Carbonate is a powder like substance which is one of the three grades of Soda Ash. But the two main grades are Soda Ash Light and Soda Ash Dense. The differences between the two grades are their particle size and density.

It is a highly soluble substance which is why it is ideally used in various chemical reaction processes. Many manufacturing plants use it in the making of colouring dyes and agents. It is also used in the manufacturing of fertilizers and synthetic detergents. Sodium carbonate or Soda ash light is known to be used in improving and treating of the alkaline levels of lakes which have been known to be affected by rains. It is used to replace phosphates which were earlier used in various household detergents and cleaning agents. Examples of these are dishwashing soaps which contain high levels of soda ash.

Sodium Bisulfite 99% is a chemical compound created by bubbling sulfur dioxide through a solution of sodium carbonate in water. It appears solid white in color with a crystalline or granular texture. Sodium bisulfite also emits a slight sulphurous odor. It is not soluble in water and decomposes at its melting point i.e. 180C.

The anhydrous sodium hypochlorite is high unstable and discomposes in an explosion. For this reason, the salt is commonly sold in the pentahydrate form which is less dangerous. Nevertheless, the pentahydrate reacts with various metals such as zinc to create a hydroxide. It also reacts with carbon dioxide in the water to form sodium carbonate. It also reacts with various nitrogen compound to form volatile nitrogen compounds.
