Sodium Hydroxide, 50 Percent (w/w), Solution, Reagent is commonly known as Caustic soda. This inorganic compound is water soluble, as well as in ethanol and methanol. The dissolution of solid Sodium Hydroxide in water creates a highly exothermic reaction. The concentrated solution is suitable for further dilution or as a raw material feedstock in chemical synthetic transformations. As a Reagent grade item, Spectrum Chemical manufactured Sodium Hydroxide met the toughest regulatory standards for quality and purity.
