Saturated vapor pressure: 0.13 Kpa (739℃)
Appearance: white crystalline powder
Solubility: easily soluble in water, ethanol, glycerin
Chemical properties:
Sodium hydroxide is corrosive to fibers, skin, glass, ceramics, etc. It releases heat when dissolved or when a concentrated solution is diluted. It can also generate a lot of heat when it reacts with inorganic acids to generate corresponding salts. It reacts with metal aluminum and zinc, non-metal boron and silicon to release hydrogen. It undergoes disproportionation reactions with halogens such as chlorine, bromine, and iodine. It can precipitate metal ions from aqueous solutions to form hydroxides. It can cause oils and fats to undergo saponification reactions to generate corresponding sodium salts of organic acids and alcohols, which is the principle of removing oil stains from fabrics.
