is hydrogen chloride hcl
Hydrogen chloride is in the gaseous form, and it has the molecular formula of HCl. It is a gas at the room temperature and colorless. This is a diatomic molecule, and the molar mass of it is 36.46 g molâ1. It has a pungent odor. The chlorine atom and the hydrogen atom of the molecule are connected via a covalent bond. This bond is polar due to more electronegativity of chlorine compared to hydrogen. Hydrogen chloride is highly soluble in water. Following is the dissociation reaction of HCl in aqueous medium. HCl +H2O â H3O+ +Clâ.
