Hydrochloric acid is a strong acid that can be used to test the pH of a substance. Litmus paper is a type of pH indicator that changes color in the presence of an acid or a base. When hydrochloric acid comes into contact with litmus paper, it will turn the paper red, indicating that the substance is acidic. This reaction occurs because the hydrogen ions in the hydrochloric acid react with the litmus paper, causing the color change. **
