Stable and stable. Hydrolysis in water. Reacts with inorganic acids to form highly toxic hy-drogen fluoride. Incompatible with glass

The molecular formula is NaF. Colorless crystal or white solid at room temperature, no odor; The aqueous solution is weakly alkaline and dissolves in hydro-fluoric acid to form sodium hy-drogen fluoride, which can corrode glass. Sod-ium fluoride is an important fluoride salt, which is widely used in wood preservative, wine fungicide, electrolytic aluminum modifier, dental fluoridation agent and so on.
