INTRODUCTION

• Hydrogen chloride (IUPAC NAME), chemical compound, HCl, a colorless,gas with an unpleasant, acrid odor

• Hydrogen chloride is a diatomic molecule, consisting o! a hydrogen atochlorine atom Cl connected "y a co#alent single "ond

• It is #ery solu"le in water and readily solu"le in alcohol and ether

• It !umes in moist air

•

$ecause o! its acidic nature, hydrogen chloride is corrosi#e, particularlypresence o! moisture

• It is not %amma"le, and the li&uid is a poor conductor o! electricity
