Sodium Fluoride Overview
Sodium fluoride is an inorganic fluoride that is both toxic and corrosive, appearing as a white crystalline powder or granular substance. It remains stable under normal temperatures and dry conditions. However, it can react with strong acids—such as hydrochloric acid and sulfuric acid—to produce highly toxic hydrofluoric acid (HF). Therefore, it is essential to avoid storing sodium fluoride together with acidic materials to ensure safety.
