Caustic soda is a chemical with industrial applications and is used by various industries. Including synthetic silk, aluminum, paper, fabric, petrochemicals, soaps and detergents, ceramics, edible oil, dairy, alcohol, cotton, and leather industries use the scale on a large scale. they do. Significant applications of caustic soda can be used in cases such as separating cellulose fibers from leginine in wood decomposition and paper pulp production or in the process of sweetening olives, controlling effluent, dyeing, degreasing, neutralizing acid in the battery industry, refining He mentioned water, plastic recycling, metal plating, washing tanks in various industries, washing glass, in the pharmaceutical industry, and so on. Of course, baking soda is used in the food industry, as mentioned, but baking soda, which is free of mercury and iron, can be used in the food industry. On the other hand, this material also has the conditions for laboratory use, because soda caustic can be used to determine the concentration of unknown acids in titration (volumetric measurement) of acid-base. For this purpose, an alkaline solution of sodium hydroxide is used under standard conditions.
Caustic soda is solid at room temperature, white and odorless. The commercial supply of this product is in solid form and in the form of flakes or granules. If it is offered in the form of a scales, it is called caustic soda flake, and if it is marketed in granular form, it will be called caustic soda granular. Liquid sodium hydroxide is not commercially available due to its hazardous conditions. That is why they produce caustic soda. Caustic soda is carried in special laminated bags because it can easily absorb ambient moisture and stick to the scales. This has led to high sensitivity in the transportation of this material.
Caustic soda has a high melting point but dissolves easily and with high intensity in water and is very dangerous in the dissolution process. In the water-soluble state, its color is clear. Caustic soda is a corrosive solution that has a higher corrosive strength when dissolved in water. The process of dissolving caustic soda in water is a thermal process and ultimately produces a solution that has a very high pH. Although caustic soda is a useful and widely used chemical for various industries, due to its high reactivity to water and in case of contact with human skin or eyes or in case of inhalation, it causes serious and compensatory injuries. It will be impossible. As a result, safety precautions, such as the use of hats, gloves, and appropriate masks, must be observed when using this material in any situation and in any industry.
