Hydrogen Fluoride

Introduction:

Hydrogen fluoride is a colorless corrosive gas or liquid, which is composed of a hydrogen atom and a fluorine atom. The aqueous solution of hydrogen fluoride is called hydrofluoric acid. Hydrogen and aluminum fluoride are raw materials for industrial production.

CAS：7664-39-3

Molecular formula:FH

Molecular weight: 20.01

Chemical properties: it is colorless, transparent to light yellow smoke liquid at normal temperature, with pungent smell, specific gravity of 0.98, slightly lighter than water, boiling point of 19.4 ℃, very volatile, and white smoke when placed in the air.
