   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.

   3 days ago · Sodium is a group 1 element and, like other alkali metals, it is a powerful reducing agent. Sodium is generally considered to be a very reactive element because it can readily lose its single valence electron. It is therefore unsurprising that sodium is not found in an isolated state and is always found bonded to other elements.
