Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns.It is highly soluble in water, and readily ...
Caustic soda is one of the common names for sodium hydroxide (NaOH), which is also known as lye. Its common name derives from its chemical identity as a sodium hydrate and because it is caustic or corrosive. In pure form, caustic soda is a waxy, white solid. It readily absorbs water and forms aqueous solutions.
Nearly all caustic soda is generated by the electrolysis of sodium chloride solution using one of three cell types: mercury, diaphragm and membrane cells. The electrolysis process produces 2.25 tonnes of 50% caustic soda with each tonne of chlorine.
Chlorine occurs naturally but not in its elemental (gas) form (as Cl 2 ). Caustic soda (usually as NaOH) is produced as a liquid. These are produced by passing an electrical current through brine (common salt dissolved in water). This is called electrolysis, a process which has been known for over 120 years. Chlorine & caustic Soda Production.
The Caustic Soda produced by the membrane cell process is most typically brought up as Membrane Grade. It conjointly contains a growing acceptance as a Rayon Grade product in all areas outside of rayon fiber production.
Anhydrous Caustic Soda (sodium hydroxide) is produced by multi-stage evaporation process and transformed into the solid state either as micro spherical particles called Prills (Pearl) or as Caustic Soda Solid (Fused).
The sodium ions are spectator ions. If the sodium hydroxide (caustic soda) is in solid form at the start of the reaction, the sodium ions enter solution, but chemically, they don’t participate in this reaction. The aluminum metal is oxidized to th...
Caustic soda is produced by the electrolysis of brine. The product is highly alkaline hydrophilic. It is a basic inorganic chemical with a wide range of applications like paper, synthetic fiber, soap, chemical seasonings, and so on.
It produces caustic soda along with chlorine and hydrogen from the electrolysis of salt brine. It is produced in five plants in Europe. Occidental Chemical Corporation (OxyChem)
