The simplest test to do in order to identify the possible presence of hydrochloric acid is to use a pH paper. Dipping it will change the color of the paper to a color that will signify that the pH is under the acid range (1-6). Hope this helps.

Answer and explanation;

The easiest way to test for hydrochloric acid is with silver nitrate solution.

-Add silver nitrate solution to the test solution in a test tube and observe the reaction. If a white precipitate forms, hydrochloric acid is present.

-Hydrochloric acid (HCI) is a strong corrosive acid that occurs by dissolving hydrogen chloride in water. It is often used as a chemical reagent and is also made naturally in the body. Most gastric acid (human digestive acid) is made of hydrochloric acid.
