Hydrofluoric Acid - an overview | ScienceDirect Topics

Hydrogen fluoride is a colorless, corrosive liquid or gas and is composed of a hydrogen atom and a fluorine atom. It has a strong, irritating odor. Hydrogen fluoride readily dissolves in water and is referred to as hydrofluoric acid (HFA) in its dissolved form. It is present in a variety of over-the-counter products at concentrations of 6–12%.

SAFETY DATA SHEET Page 1 of 6 Aluminum Brightener

: Severe hydrofluoric acid exposure may result in systematic fluoride poisoning. Hydrofluoric acid can deeply penetrate into tissues. Additionally, the free fluoride ions can bind calcium ions at the cell membrane, increase the potassium permeability and alter the membrane electrical potential. This results in spontaneous depolarization of the
