It has the commonness of strong alkali, strong corrosion and high chemical reactivity: it is strong alkaline, can make phenolphthalein red and have a sense of smoothness;

Highly corrosive, can corrode metal, fiber, animal tissue, glass, ceramics, etc. Non-corrosive to nickel, silver, gold, platinum, etc.

Etch certain plastics, rubbers and coatings; React with aluminum and zinc, non-metallic boron and silicon to release hydrogen;

Disproportionation 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, and produce the corresponding organic acid sodium salt and alcohol;

React with various acids, halogenated organic matter, nitro-containing organic matter and ethylene glycol, etc.

Concentrated alkali is easy to react with various reducing sugars (such as sugar, galactose, maltose, etc.) to produce carbon monoxide.

Soluble in water, heat release when dissolved. Soluble in ethanol and glycerol; Insoluble in acetone and ether.
