    Application

    Sodium carbonate has wide applications in various kinds of fields around the world. One of most important application of sodium carbonate is for the manufacturing of glass. Based on statistics information, about half of the total production of sodium carbonate is used for the manufacturing of glass. During the production of glass, sodium carbonate acts as a flux in the melting of silica. In addition, as a strong chemical base, it is used in the manufacturing of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner. In addition, it can also be used for tissue digestion, dissolving amphoteric metals and compounds, food preparation as well as acting as a cleaning agent.


    The following is our analysis of the common fields of sodium carbonate

    1.Water softening:
    Hard water usually contains calcium or magnesium ions. Sodium carbonate is used for
    removing these ions and replacing them with sodium ions.
    Sodium carbonate is a water-soluble source of carbonate. The calcium and magnesium ions form insoluble solid precipitates upon treatment with carbonate ions:
    Ca2+ + CO2−3 → CaCO3 (s)
    The water is softened because it no longer contains dissolved calcium ions and magnesium ions.
    Sodium carbonate helps soften water by removing Ca²⁺, Mg²⁺, and other ions that make it hard water. When all these ions are treated with carbonate ions, they form insoluble solid precipitates. Furthermore, soft water has many benefits. It reduces soap wastage, increases the life of pipes and fittings, and keeps them safe from rust.

    2. Glass manufacture:
    Soda ash and caustic soda are required in the manufacture of glass. Sodium carbonate,Na₂CO₃, serves as a silica flux. It reduces the melting point of the mixture without unique materials and inexpensively achieves ‘soda-lime glass.’
    Sodium carbonate serves as a flux for silica (SiO2, melting point 1,713 °C), lowering the melting point of the mixture to something achievable without special materials. This "soda glass" is mildly water-soluble, so some calcium carbonate is added to the melt mixture to make the glass insoluble.
    Bottle and window glass ("soda-lime glass" with transistion temperature ~570 °C) is made by melting such mixtures of sodium carbonate, calcium carbonate, and silica sand (silicon dioxide (SiO2)).
    When these materials are heated, the carbonates release carbon dioxide. In this way, sodium carbonate is a source of sodium oxide.Soda-lime glass has been the most common form of glass for centuries. It is also a key input for tableware glass manufacturing.

    3. Food additives and cooking:
    Sodium carbonate is a food additive that acts as an anti caking agent, acidity regulator, stabiliser, and raising agent. It has a variety of culinary applications. It is also added to some food items to enhance their taste.

    Sodium carbonate has several uses in cuisine, largely because it is a stronger base than baking soda (sodium bicarbonate) but weaker than lye (which may refer to sodium hydroxide or, less commonly, potassium hydroxide). Alkalinity affects gluten production in kneaded doughs, and also improves browning by reducing the temperature at which the Maillard reaction occurs. To take advantage of the former effect, sodium carbonate is therefore one of the components of kansui , a solution of alkaline salts used to give Japanese ramen noodles their characteristic flavor and chewy texture; a similar solution is used in Chinese cuisine to make lamian, for similar reasons. Cantonese bakers similarly use sodium carbonate as a substitute for lye-water to give moon cakes their characteristic texture and improve browning.
    In German cuisine (and Central European cuisine more broadly), breads such as pretzels and lye rolls traditionally treated with lye to improve browning can be treated instead with sodium carbonate; sodium carbonate does not produce quite as strong a browning as lye, but is much safer and easier to work with.Sodium carbonate is used in the production of sherbet powder. The cooling and fizzing sensation results from the endothermic reaction between sodium carbonate and a weak acid, commonly citric acid, releasing carbon dioxide gas, which occurs when the sherbet is moistened by saliva.
    Sodium carbonate also finds use in food industry as a food additive (E500) as an acidity regulator, anti caking agent, raising agent, and stabilizer. It is also used in the production of snus to stabilize the pH of the final product.
    While it is less likely to cause chemical burns than lye, care must still be taken when working with sodium carbonate in the kitchen, as it is corrosive to aluminum cookware, utensils, and foil.

    4. Detergent Manufacture
    Sodium carbonate can replace the phosphates that are used in making household detergents.
    Also, there are various cleaning products and dishwashing soaps that contain soda ash in their formulations.
    1) It can help in removing stains, alcohol, and grease on clothes – also in coffee pots and espresso makers.
    2) It can increase the alkaline level in swimming pools which can help in maintaining the PH Levels to balance the water.
    3) It can also be used for dying clothes.
    4) It can effectively clean the air.
    5) It can soften water.
    6) As a cleansing agent for domestic purposes like washing clothes. Sodium carbonate is a component of many dry soap powders. It has detergent properties through the process of saponification, which converts fats and grease to water-soluble salts (soaps, actually).
    7) It is used for lowering the hardness of water (see § Water softening).
    8) It is used in the manufacture of glass, soap, and paper (see § Glass manufacture).
    9) It is used in the manufacture of sodium compounds like borax.
