Viscosity of Hydrofluoric Acid 48%


Hydrofluoric acid is a solution of hydrogen fluoride in water with the molecular formula HF. It is a precursor to almost all fluorine compounds, including pharmaceuticals such as fluoxetine (Prozac), diverse materials such as PTFE (Teflon), and elemental fluorine itself.

It is a colorless solution that is highly corrosive, capable of dissolving many materials, especially oxides. Its well-known ability to dissolve glass has already been known since the 17th century. Hydrogen fluoride gas is an acute poison that may immediately and permanently damage lungs and the corneas of the eyes. Aqueous hydrofluoric acid is a contact poison with the potential for deep, initially painless burns and ensuing tissue death.
