What is the common name for HCl?

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

Answer: (A)

The common name for HCl is hydrochloric acid. This name reflects the compound’s composition: "hydro" indicates the presence of hydrogen, "chlor" refers to chlorine, and "ic" indicates that it is a strong acid. Hydrochloric acid is widely known and used in various applications such as in laboratories and industry, where it serves as a strong acid and a powerful electrolyte. The other compounds listed do not correspond to HCl. Sulfuric acid, for instance, consists of sulfur, oxygen, and hydrogen and has a different chemical formula (H₂SO₄). Hydrosulfuric acid, which is another name for hydrogen sulfide (H₂S), is also distinct and unrelated. Hydrofluoric acid refers to HF and is a weak acid primarily used in various industrial applications but is also not related to HCl. Thus, hydrochloric acid is the correct and commonly recognized name for HCl.
