Which statement is true about hydrocholoric acid?

Hydrochloric acid is indeed a strong acid primarily used in industrial processes, which makes the chosen statement true. It has a high concentration of hydrogen ions, giving it its strong acidic properties. This powerful acid is often utilized for pH adjustment, metal cleaning, and various chemical reactions in industrial applications.

The other options do not accurately describe hydrochloric acid. While there are many weak acids used in cosmetics, hydrochloric acid is not one of them and is typically too potent for such applications. It is also not a natural acid found in fruits; instead, fruits contain organic acids like citric acid or malic acid. Lastly, the pH of hydrochloric acid is significantly lower than neutral, usually around 1 or lower, depending on its concentration, confirming why the statement about having a neutral pH is incorrect.
