Chemical Property:

Sodium hydroxide has a corrosive effect on fibers, skin, glass, ceramics, etc. When dissolved or diluted with a concentrated solution, it will release heat; Neutralization reaction with inorganic acids can also generate a large amount of heat, generating corresponding salts; React with metal aluminum and zinc, non-metallic boron and silicon to release hydrogen from the Chemical book; Disproportionation reaction occurs with halogens such as chlorine, bromine, and iodine. Able to precipitate metal ions from aqueous solutions into hydroxides; It can make the grease undergo saponification and generate the corresponding sodium salt and alcohol of organic acid, which is the principle of removing the oil stain on the fabric.

Application:

Sodium hydroxide (NaOH) is one of the most useful industrial sodium compounds. It is also known as lye or caustic soda and is one of the strongest base alkalis (high pH value) on the household market. It is used as a drain and oven cleaner, and it saponifies fats in the manufacture of soap. It must be used with care because it is also capable of producing serious skin burns.
