Hydrogen Chloride

CAS RN: 7647-01-0

Volatilization

The Henry's Law constant for hydrogen chloride is 2.04X10+6 mol/L atm (4.90X10-10 cu m atm/mol)(1). This Henry's Law constant indicates that hydrogen chloride is expected to be essentially nonvolatile from water and moist soil surfaces(2). Hydrogen chloride will evaporate from dry soil surfaces(3).
