natriumhydrokselin

Natriumhydrokselin is the Swedish name for sodium hydroxide, a highly caustic inorganic compound with the chemical formula NaOH. It is also known as lye or caustic soda. In its pure form, sodium hydroxide is a white solid, often found in pellet, flake, or granular form, as well as in solutions of various concentrations. It is an ionic compound, consisting of sodium cations (Na+) and hydroxide anions (OH-).

Sodium hydroxide is a strong base, meaning it readily dissociates in water to produce hydroxide ions. This property makes it highly reactive and corrosive. It reacts exothermically with acids, neutralizing them. It also reacts with certain metals, such as aluminum and zinc, releasing hydrogen gas. Sodium hydroxide is hygroscopic, meaning it absorbs moisture from the air, and it can react with carbon dioxide in the air to form sodium carbonate.

Industrially, sodium hydroxide is a crucial chemical. It is produced primarily through the electrolysis of sodium chloride (salt) solution, a process known as the chlor-alkali process. Its applications are widespread, including in the manufacture of pulp and paper, textiles, soaps and detergents, and petroleum products. It is also used in water treatment to adjust pH and in the production of various chemicals. Due to its corrosive nature, proper handling precautions are essential when working with sodium hydroxide, including the use of protective equipment.
