Hydrofluoric Acid
Hydrofluoric acid (17870)
Aqueous 70% Solution
Overview
Our 70% HF solution is an aqueous grade that is a clear, colorless, corrosive fuming liquid with a sharp, stinging odor. It is 100% soluble in water and is not flammable.
70% HF is highly hazardous and needs to be handled and used with rigorous safety precautions. It can cause severe burns to all parts of the body in liquid and vapor forms. Specialized medical treatment is required for any exposure to 70% HF.

Safety Information
- Chemical Stability
- Stable under normal conditions
- Corrosivity
- Corrosive to metals
- Ignition Temperature
- Not applicable
- Incompatible Materials
- Contact with alkalies and some oxides cause strong violent exothermic reactions
- Contact with metals will yield hydrogen gas, a fire and explosive reactive hazard
- Glass and silicate-containing materials are attacked
- HF contact with carbonates, sulfides and cyanides yield toxic gases such as carbon dioxide, hydrogen sulfide and hydrogen cyanide
- HF contact with glass, concrete and other silicon bearing
- On dilution or dissolving in water, considerable heating always occurs
- Pressure buildup from this process has been known to rupture glass containers
- When diluting, add acids to water, never the other way around
- Thermal Decomposition
- Fire or intense heat may cause violent rupture of packages.
