The difference between Hydrogen chloride and hydrochloric acid:
01.Hydrogen chloride and hydrochloric acid have different properties: Hydrogen chloride is a gas; Hydrochloric acid is an aqueous mixture of Hydrogen chloride. Concentrated hydrochloric acid is nothing more than hydrogen chloride. Hydrogen chloride is a pure covalent compound that is highly corrosive, but not very corrosive in the absence of moisture.
Hydrogen chloride consists of hydrogen chloride molecules; Hydrochloric acid is composed of water molecules, hydrogen ions, chloride ions and a small amount of hydroxide ions. Hydrogen chloride is a colorless, nonflammable gas that has a pungent odor and is heavier than air. The moist air will produce white fog. Soluble in water and produce hydrochloric acid.
03.Hydrogen chloride and hydrochloric acid have different chemical bonds:
Hydrogen chloride is a covalent bond, hydrochloric acid is an ionic bond.
Hydrochloric acid, commonly known as hydrochloric acid, is an aqueous solution of hydrogen chloride gas, which is a colorless transparent monadic strong acid. Hydrochloric acid is extremely volatile, so when you open the container of concentrated hydrochloric acid, you can see a white fog on it, which is actually small droplets of hydrochloric acid produced by the combination of hydrogen chloride volatilization and water vapor in the air. Pure hydrochloric acid is a colorless liquid that fogs in air (due to the strong volatility of hydrochloric acid) and has a pungent sour taste. Crude hydrochloric acid is yellowish because it contains ferric chloride impurities.
