Use this practical to investigate how solutions of the halogens inhibit the growth of bacteria and which is most effective. Syringes should not be allowed to become wet, or the plungers will stick inside the barrels. What happens when magnesium reacts with hydrochloric acid? Hydrochloric acid is corrosive and toxic, and hydrogen gas is also flammable. The ratio of the cumulative reaction duration above gives 104.8 sec/58.8 sec = 1.78. Research Question: If magnesium ribbon is replaced with an equivalent weight of powered magnesium, does the rate of reaction between magnesium and hydrochloric acid double? 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. 2.0. Hydrochloric acid is corrosive. Illustration of a single displacement reaction. Therefore, considering concentration factor and surface are factor of reactants it is evident that the rate reaction curve trends would not be linear as expected, but rather exponential. This occurs only when the metal is more reactive than Hydrogen (check reactivity series ). Temperature influences the rates of reaction through kinetic energy, such that high temperatures increase the kinetic energy of reacting molecules therefore causing frequent collisions, which form products faster. Clark (2002) explains that, finely divided chemical solids have greater surface area than chemical solids in lumps.
