What is the name of the substance with the chemical formula HCl?

• A. Hydrochloric acid
• B. Hydrosulfuric acid
• C. Hydronitric acid
• D. Hydrofluoric acid

Answer: (A)

The substance with the chemical formula HCl is known as hydrochloric acid. This is a strong acid formed when hydrogen chloride gas dissolves in water. Hydrochloric acid is commonly used in various applications, including laboratory experiments, food processing, and metal cleaning. It is characterized by its ability to dissociate completely in water into hydrogen ions (H⁺) and chloride ions (Cl⁻), resulting in a solution with a low pH. In contrast, hydrosulfuric acid, which can also be referred to as hydrogen sulfide in its gaseous state (H₂S), does not correlate with the formula HCl. Similarly, hydronitric acid refers to nitric acid (HNO₃), and hydrofluoric acid is a different compound entirely (HF). Each of these acids has distinct properties and uses that differentiate them from hydrochloric acid, validating hydrochloric acid as the correct identification for the formula HCl.
