Oct 14, 2022 · Sodium hydroxide (NaOH), also known as caustic soda or lye, is a highly versatile substance used in a variety of manufacturing processes. Sodium hydroxide is a co-product of chlorine production. Key Points/Overview. Uses & Benefits.
- Sodium hydroxide, known as lye and caustic soda, is an inorganic compound with the formula NaOH. FactSnippet No. 1,009,005.
- Sodium hydroxide is used in many industries: in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents, and as a drain cleaner.
- Similar to the hydration of sulfuric acid, dissolution of solid sodium hydroxide in water is a highly exothermic reaction where a large amount of heat is liberated, posing a threat to safety through the possibility of splashing.
- The viscosity of sodium hydroxide solutions plays a direct role in its application as well as its storage. FactSnippet No. 1,009,008.
May 21, 2018 · Interesting Facts. Solutions of sodium hydroxide are made by adding the solid compound to water, and never water to the solid. The reason is that large amounts of heat are generated when sodium hydroxide dissolves in water. That heat is absorbed by water, but would not be absorbed by solid sodium hydroxide.
Properties of Sodium Hydroxide – NaOH. Sodium Hydroxide is a white, translucent crystalline solid. It is commonly referred to as caustic soda due to its corrosive action on many substances; it decomposes proteins at room temperatures and may cause chemical burns to human bodies.
Chemical Properties. Sodium hydroxide is a strong base and ranks as one of the most commonly used alkalis. It has a high affinity for water, undergoing exothermic reactions when combined with it, which can be used to generate considerable amounts of heat. This is often exploited in many applications that require the increase of temperature.
