PART II PROCEDURE Explanation: Magnesium, Mg, will react with hydrochloric acid, HCl, to produce aqueous magnesium chloride, MgCl2, and hydrogen gas, H2, which bubbles out of solution. 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. For stance, magnesium metal reacts with hydrochloric to form magnesium chloride salt while displacing hydrogen from the acid as hydrogen gas. Limiting Reactant: Reaction of Mg with HCl. Latest answer posted December 07, 2018 at 12:04:01 PM. eNotes.com will help you with any book or any question. Pour hydrochloric acid into the Petri dish to a depth of about 5 mm. Add the first of the powdered metals and stir the mixture with the thermometer. Turn on the camera and focus it. At higher acid concentration, the rates of bubble forming were rapid than those in lower acid concentrations were. While the salt remains in the water as part of a solution, the gas produced will float .
