Standard Operating Procedure - Chemical Engineering- nitrile gloves hydrofluoric acid pka formula chemistry ,Hydrofluoric Acid (HF) 2 Date: 9/12/2012 UCLA- EH&S GKM/PY Uses : HF is used to etch glass. Because of its ability to dissolve oxides, hydrofluoric acid is useful for dissolving rock samples (usually powdered) prior to analysis. The ability of hydrofluoric acid to dissolve metal oxides is the basis of several applications.Guidelines for the Safe Use of Hydrofluoric AcidMar 11, 2013·Guidelines for the Safe Use of Hydrofluoric Acid. A. INTRODUCTION. Hydrofluoric acid (HF) has a number of physical, chemical, and toxicological properties that make it especially hazardous to handle. Both anhydrous hydrofluoric acid and aqueous solutions are clear, colorless, and corrosive liquids.

Fluorosulfonic acid | HSO3F - PubChem

FLUOROSULFONIC ACID is very strongly acidic [Merck]. Reacts exothermically with chemical bases (examples: amines, amides, and inorganic hydroxides). These reactions can generate dangerously large amounts of heat in small spaces. Reacts violently with water to generate hydrofluoric acid and sulfuric acid.
