What are the various applications of Sodium Carbonate?

19 July 2022

The chemical compound sodium carbonate is classified as inorganic. Commonly referred to as "Soda ash," a sodium carbonate is a form of sodium oxide. Trona is processed to produce soda ash. Trona is a double salt made up of sodium hydrogen carbonate as well as sodium carbonate, both of which are byproducts of the various evaporation processes that occur in lakes.


Among the heavy chemicals, none is more fundamental than sodium carbonate, sometimes known as soda ash or washing soda. It is much safer to work with than sodium hydroxide since it does not corrode.


Sodium carbonate (also known as washing soda) is used for many things, let's check out a few applications of Sodium Carbonate listed by Palvi FZE - one of the top-ranking Sodium Carbonate suppliers in Qatar.


  • Sodium carbonate, sometimes known as washing soda, is a common household cleaner. Many types of dry soap powder have sodium carbonate as an ingredient.
  • For both short- and long-term water hardness mitigation, this device is indispensable.
  • Glass, soap, and paper are just a few of the products that incorporate it.
  • It plays a role in the production of borax and other sodium compounds.

Glass manufacture:

As a flux for silica, sodium carbonate reduces the melting point of the resulting combination to a level that may be reached without any unusual ingredients. A little addition of calcium carbonate to the melted mixture of this "soda glass," will make it insoluble in water. Glass for bottles and windows (soda-lime glass) is produced by melting silica sand, calcium carbonate, as well as sodium carbonate together. Carbon dioxide is produced by the carbonates in these materials when they are heated. Sodium carbonate can be used to produce sodium oxide in this fashion. For generations, soda-lime glass has been the standard material for making glasses. To top it all off, it's a necessary component in making high-quality glassware for the table. Palvi FZE is an excellent as well as a noted Sodium Carbonate distributor in Qatar that can fulfil all of your industrial chemical needs.

Water softening:

Calcium and magnesium compounds are the most common types of dissolved solids in hard water. Sodium carbonate can be used to reduce or eliminate the water's hardness temporarily or permanently.


Since sodium carbonate dissolves in water while magnesium and calcium carbonate do not, sodium carbonate is commonly used to soften water by eliminating Ca2+ and Mg2+.


Because the calcium and magnesium ions in the water have been removed, the water has been softened.

Food additive:

Since it is a more potent base as compared to baking soda but less potent than lye, sodium carbonate finds several applications in the kitchen. Kneaded doughs' gluten synthesis is influenced by alkalinity, and browning is enhanced since the Maillard reaction temperature is lowered. To achieve the former effect, sodium carbonate is included in kansui, an alkaline salt solution that is used to impart the distinctive flavour and chewy texture that is so characteristic of Japanese ramen noodles; a solution with comparable properties is used to prepare lamian in Chinese cuisine. Sodium Carbonate manufactured and exported by one of the most prominent as well as trustworthy Sodium Carbonate exporters in Qatar can be used as a food additive.


Similarly, when making moon cakes, Cantonese bakers employ sodium carbonate in place of lye-water to get the same results in terms of texture and browning. Sodium carbonate can be used instead of lye to enhance the browning of bread in German cooking (and Central European cooking more generally), including pretzels and lye rolls. Sodium carbonate does not generate quite as strong a browning as lye, but it is considerably safer and easier to deal with.


Sherbet powder uses sodium carbonate in its manufacturing. When sherbet is mixed with saliva, a chilling and fizzing feeling is produced due to the endothermic reaction between a weak acid and sodium carbonate, generating carbon dioxide gas.


As a food additive (E500), sodium carbonate is used to control acidity, prevent caking, increase volume, and stabilise food. In order to maintain a consistent pH level, it is also utilised during the snus manufacturing process.


Sodium carbonate is less prone to produce chemical burns than lye, but it still requires caution in the kitchen because it can corrode aluminium.

Other applications:

As a strong base, sodium carbonate has several applications. The fact that it is less expensive than sodium hydroxide and easier to work with makes it the go-to alkali in many industrial settings. Its mildness makes it ideal for use in the home.


For the most part, developing photographic film requires a stable alkaline environment, and this is where its pH-regulating abilities come in handy. Adding it to pool and aquarium water helps keep the water at the ideal carbonate hardness (KH) as well as pH. Sodium carbonate is used in fibre-reactive dyeing to facilitate the chemical interaction of the dye with cellulose (plant) fibres, either prior to dying (in the case of tie-dyes) or following dyeing (in the case of dye painting) (for immersion dyeing). Not only is it utilised alongside CaO and other moderately basic compounds as a float conditioner in the process of froth flotation to keep the pH in a desirable range, but it is also used in the process itself to initiate flotation.
