Sodium hydroxide (NaOH) also known as caustic soda is a water soluble inorganic base with a wide range of industrial application such as titration, dissolution testing and in impinger to remove acidic gases. It participates in the oxidation of glycerol catalyzed by Au/charcoal or Au/graphite. It participates in solvent-free aldol condensation reaction.
