Also called Caustic Soda and substitutes for Red Devil Lye, sodium hydroxide is a white deliquescent solid soluble in water, alcohol and glycerol. It has uses in multiple manufacturing processes.
In the lab, sodium hydroxide is often used as a base for titrations, a method of determining the concentration of an acidic solution by slowly adding a base until the acid is neutralized. It can also be used to adjust the pH of a solution, dissolve certain types of organic compounds, and prepare certain types of compounds.
Sodium hydroxide is essential in soap production because it helps convert fats and oils into soap through a process called saponification. Saponification is a chemical reaction in which sodium hydroxide reacts with fats and oils to create both soap and glycerol.
Sodium hydroxide plays a role in the preparation and maintenance of welding equipment and materials. Its strong base properties make it effective for cleaning, flux preparation, and material treatment.
