What is the name of the acid formed when hydrogen chloride gas dissolves in water?

When hydrogen chloride gas dissolves in water, it forms hydrochloric acid. This occurs because hydrogen chloride (HCl) ionizes in water to produce hydrogen ions (H⁺) and chloride ions (Cl⁻). The resulting aqueous solution is known as hydrochloric acid, which is a strong acid commonly used in various applications, including laboratory use and industrial processes.

The other options are different types of acids that form from other substances. Sulfuric acid, for example, is derived from sulfur trioxide and water, while nitric acid is formed from nitrogen dioxide and water. Acetic acid, on the other hand, is an organic acid typically derived from the fermentation of ethanol. Each of these acids has distinct chemical properties and uses, but only hydrochloric acid is created directly when hydrogen chloride gas is dissolved in water.
