Sodium Chloride CAS#7647-14-5
Sodium fluoride is a toxic and corrosive inorganic fluoride, available as white powder or granules. It remains stable at ambient temperature under dry conditions. Nevertheless, upon contact with strong acids including hydrochloric acid and sulfuric acid, it reacts to generate highly‑toxic hydrofluoric acid (HF). Therefore, storage alongside acidic materials must be strictly prohibited.
