Product description
Sodium hydroxide, also known as caustic soda, caustic soda, caustic soda, caustic soda tablet, is an inorganic compound with the chemical formula NaOH and a relative molecular weight of 39.9970.
Sodium hydroxide has a strong alkaline, extremely corrosive, can be used as acid neutralizer, with masking agent, precipitating agent, precipitation masking agent, color development agent, saponification agent, peeling agent, detergent, etc., the use is very wide.
Sodium hydroxide has a corrosive effect on fibers, skin, glass, ceramics, etc., and will release heat when dissolved or diluted in concentrated solution. The neutralization reaction with inorganic acid can also produce a lot of heat and generate the corresponding salts. React with aluminum and zinc, non-metallic boron and silicon to release hydrogen; Disproportionation reaction occurs with halogens such as chlorine, bromine and iodine. Can precipitate metal ions from aqueous solution to become hydroxide; It can make the oil saponification reaction, generate the corresponding organic acid sodium salt and alcohol, which is the principle of removing the oil on the fabric.
