Hydrofluoric Acid HF

Hydrofluoric Acid HF is a highly corrosive aqueous solution of hydrogen fluoride gas dissolved in water. It is a colorless to pale yellow fuming liquid with a strong pungent odor. Unlike other mineral acids, HF is a weak acid chemically but uniquely reactive due to its ability to dissolve silica and glass, and penetrate tissues deeply. This makes it invaluable in numerous industrial, laboratory, and specialized applications but also highly hazardous.
