Sodium Hydroxide Solution 50% AR 100ml

SKU : I-9058.0100
CAS : 1310-73-2
Formula : NaOH
Grade : Analytical Reagent

Sodium Hydroxide 50% is primarily used as a highly concentrated industrial chemical reactant and neutralizing agent. Due to its high alkalinity, it is essential for breaking down organic matter and controlling pH levels across several major industries.

Primary Industrial Applications
  • Pulp and Paper: This is the largest consumer of 50% NaOH . It is used in the Kraft process to separate lignin from cellulose fibers and acts as a bleaching agent to improve paper quality .
  • Chemical Manufacturing: Serves as a base for producing diverse chemicals, including sodium salts, synthetic detergents, and plasticizers. It is also critical in the production of rayon and cellophane.
  • Water Treatment: Facilities use it to regulate pH levels in drinking water and neutralize acidic wastewater. It also aids in removing heavy metals like lead and copper by causing them to precipitate.
  • Aluminum Industry: Essential in the Bayer process, where it dissolves alumina from bauxite ore while leaving impurities like iron oxide behind.
  • Petroleum Refining: Used for caustic washing to remove sulfurous impurities (like hydrogen sulfide) and CO₂ from crude oil and refined fuels.
  • Soaps and Detergents: Acts as the primary agent in saponification, reacting with fats and oils to produce hard bar soaps and industrial cleaning compounds.

Sodium Hydroxide Solution 50% is a highly concentrated, viscous, and colorless aqueous solution containing roughly 50% NaOH by weight. It is a powerful base (caustic soda/lye) used in industrial applications, such as chemical synthesis, pulp/paper manufacturing, detergents, and industrial cleaning. It causes severe skin burns and eye damage.In analytical chemistry, a 50% (w/w) sodium hydroxide solution is frequently called a Sorensen solution. It is the standard starting point for preparing precise diluted solutions, such as 1N or 0.1N NaOH. Because sodium carbonate is nearly insoluble in 50% NaOH, it settles to the bottom of the bottle. This allows chemists to pipette pure, carbonate-free hydroxide from the middle of the solution, which is essential for accurate titration

Hello
Can we help you?
Labotiq focuses on a practical and precise field: laboratory supplies, chemical reagents, equipment, and plastic labware. This kind of work is all about accuracy, safety, and trust, because even small details can affect the final result. The same idea is becoming more relevant in digital entertainment, where choosing a platform also means paying attention to reliability, transparency, and user protection.Online entertainment has turned into an everyday habit, from streaming and mobile games to casino-style platforms and interactive services. Still, a good digital experience starts with clear rules, secure payments, licensed operators, and easy-to-understand information. Anyone interested in safe online leisure and the Spanish gambling market can find a useful reference in mejores casinos en España. The topic is not only about fun, but also about choosing platforms carefully, understanding how regulation works, and avoiding random decisions when money and personal data are involved.That creates a simple connection between the two areas. Labotiq supports laboratories with dependable products for controlled work, while trusted information about digital entertainment helps users feel more confident online. When reliability comes first, both laboratory processes and online services become easier to understand, safer to use, and more valuable in everyday life.
