NaOH (caustic soda)
hydroxide (NaOH), also known as caustic soda, is a strong base that occurs at room temperature in form . It consists of (Na + ) and hydroxide (OH – ). It is very soluble in water. Its is transparent and often called . Concentrated, it is, just like sodium hydroxide in the solid state, particularly corrosive.
Use of sodium hydroxide or caustic soda
Sodium hydroxide is often used in the chemical industry to control an alkaline medium or regulate the acidity of a process. It is also used in the manufacture of, the treatment of natural fibers or the oil industry. He is also the main agent of the .
Production of sodium hydroxide
Almost all of the sodium hydroxide is now produced byof . Sodium hydroxide can also be obtained through a caustic reaction from natural sodium carbonate present in some and vegetable ashes:
Na 2 CO 3 + Ca (OH) 2 → CaCO 3 + 2 NaOH
The dangers of sodium hydroxide
The sodium hydroxide-water mixture is highlyand can cause dangerous splashing. Because soda is irritating and corrosive, both for the skin and for the and the respiratory and digestive tracts. It must therefore be handled with care.
