Introduction (Sodium Hydroxide)
Sodium hydroxide, also known as caustic soda, caustic soda and caustic soda, is an inorganic compound with the chemical formula of NaOH. Sodium hydroxide is strongly alkaline and highly corrosive. It can be used as acid neutralizer, coordination masking agent, precipitant, precipitation masking agent, color developer, saponifier, peeling agent, detergent, etc. it is widely used.

Caustic soda crystallizes at low temperatures. Keep storage temperatures controlled in the range 85 F to 100 F (29 C to 38 C). If the temperature drops below 65 F (16 C), the viscosity of the product increases, which may affect its performance.
