NaOH is a strong base?

NaOH is a strong base :

NaOH (caustic soda)

Sodium hydroxide (NaOH), also known as caustic soda, is a strong base that occurs at room temperature in solid form . It consists of cations  of sodium (Na + ) and anions hydroxide (OH  ). It is very soluble in water. Its aqueous solution is transparent and often called soda . 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 paper pulp , the treatment of natural fibers or the oil industry. He is also the main agent of the pipe openers .

Production of sodium hydroxide

Almost all of the sodium hydroxide is now produced by electrolysis of brines . Sodium hydroxide can also be obtained through a caustic reaction from natural sodium carbonate present in some ores 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 highly exothermic and can cause dangerous splashing. Because soda is irritating and corrosive, both for the skin and for the eyes and the respiratory and digestive tracts. It must therefore be handled with care.

Sodium hydroxide and pH of water

Soda tends to raise the pH of streams. What to threaten the fauna and flora aquatic.
