NaOH compounds are called sodium hydroxide, because they contain Na + (sodium) and anion OH- (hydroxide). As in binary ionic compounds, when a metal that can form multiple cations is present, a Roman numeral is required to specify the charge on the cation. For example, feso4 compounds are called iron (ii) sulfate, because it contains Fe2 +
Sodium hydroxide is a corrosive white crystal solid that is ready to absorb moisture until dissolved. You can also buy sodium hydroxide in powder and liquid form. Usually called caustic soda, or lye, sodium hydroxide is the most widely used in alkaline industry. This is very corrosive to animal and vegetable tissues.

Purification can be made in the tank (in this case it is called batch purification or tank) or in a sustainable system. Sulfuric acid and sodium hydroxide are among the products produced in the largest number by the chemical industry, and most of the chemical processes involve acid or bases as reactants or as catalysts.
Chlorine and caustic soda are produced simultaneously with the decomposition of electrolytic salt (sodium chloride) -has become the principal source of chlorine during the 20th century.
