Syringes should not be allowed to become wet, or the plungers will stick inside the barrels. 3. Importantly, suitable acid-base indicators can be used to detect the end of the reaction accurately. For instance hydrogen bubbles block magnesium surface or blow the magnesium to the surface of the acid solution therefore, slowing down the reaction. Even if you don't want to stud. This is because the hydrogen ions (H+) from the acid I have a large binding surface on magnesium metal but later, the surface area diminishes due to other factors in the reaction. Hydrochloric acid is a corrosive liquid. 3.
