   Why is NaOH called sodium hydroxide?

   • For example, the compound NaOH is called sodium hydroxide, because it contains the Na + (sodium) cation and the OH − (hydroxide) anion. 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.

   What is sodium hydroxide used for?

   • In petroleum refining, it removes sulfuric and organic acids. In soapmaking, it acts on natural fats or oils, such as tallow or vegetable oil, to produce sodium fatty acid salt (soap) and glycerin (or glycerol); this saponification reaction is the basis for all soapmaking. In papermaking, sodium hydroxide is used to break down wood into pulp.

   4 days ago · Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide is used in soap manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals including humans. Sodium is an essential element for all animals and some plants.
