Is hydrogen chloride a gas?

By definition, hydrogen chloride is a gas. The hydrogen chloride molecule consists of one chlorine atom and one hydrogen atom, and is a colorless gas with a pungent odor. Its aqueous solution is commonly known as hydrochloric acid and its scientific name is hydrochloric acid. The molecular weight is 36.46. Hydrogen chloride is very soluble in water, and 1 volume of water can dissolve about 500 volumes of hydrogen chloride.

Gas is one of the four states of basic matter (the other three are solid, liquid, and plasma).

Gases can be composed of a single atom (such as a noble gas), a monomer molecule made of one element (such as oxygen), a compound molecule made of several elements (such as carbon dioxide), and so on. A gas mixture may include a variety of gaseous substances, such as air. The significant difference between gases, liquids, and solids is the large spacing between the gas particles. This interval makes it difficult for the human eye to perceive the colorless gas.

A gas is a fluid like a liquid. Flow, deformation. Unlike liquids, gases are compressible. If there are no limits (containers and force fields), the gas can diffuse and its volume is not limited and is not fixed. The atoms and molecules of a gas can move freely with each other.

It can be seen from the above that hydrogen chloride is a gas.
