Chemical appearance:
Caustic soda pearls appear as white spherical or semi-spherical granules with slightly perceptible color. Caustic soda pearls are water-soluble with an exothermic reaction, and they depict stability in normal conditions. Sodium hydroxide is a highly alkaline substance that dissociates completely in water into sodium and hydroxyl ions.
Chemical application and strengths:
-
- Caustic soda pearls or Sodium Hydroxide is one of the important inorganic materials for various industries all over the world. The major demand for caustic soda is evident in the paper industry for the pulping and bleaching process. Caustic soda is also a crucial raw material in aluminum production for dissolving bauxite ore.
-
- Caustic soda also finds many uses in the applications for degreasing and treatment of packaging in the food industry. The use of caustic soda is also prominent in chemical processing as a basic feedstock for various downstream products like plastics, solvents, etc.
-
- Caustic soda pearls also help in engendering the saponification of vegetable oils and fats required for manufacturing soaps. Caustic soda also finds applications in the textile industry for chemical processing of cotton. Most important of all, caustic soda is significantly important for the natural gas industry, where it helps in the production and processing of petroleum products.
-
- Caustic soda is also important for elution stripping of gold that is adsorbed onto activated carbon. The mixture of caustic soda and cyanide interacts with carbon for extracting gold from the carbon. Special conditions of temperature, pH, and the flow rate of elution are highly important to the effectiveness of caustic soda in elution stripping.
- Caustic soda also finds small-scale applications such as paint stripping, chemical analysis, and aluminum etching. Furthermore, caustic soda is also used in various domestic products such as drain cleaners, oven cleaners, and other home-cleaning products.
