Rates of Reaction: Magnesium Strips and Hydrochloric Acid

Introduction

Rates of reaction occur when two chemicals bond. The chemical bonds can be either very strong or very weak.

I expect that when I add magnesium to the hydrochloric acid that depending on the amount of hydrochloric acid that the acid will eventually dissolve the magnesium and consequently produce hydrogen gas. All chemical reactions involve reactants. When these reactants are mixed together they cause a chemical reaction to occur which will make products. The reactants that I will use are hydrochloric acid and magnesium. I predict that the chemical reaction will take place as soon as the magnesium is dropped into the hydrochloric acid. Magnesium chloride and hydrogen gas are the products formed during this reaction. The formula equation for this experiment is:

Magnesium + Hydrochloric acid = Magnesium Chloride + Hydrogen

Mg + 2HCl = MgCl2 + H2

The reason that the magnesium reacts with hydrochloric acid is because the magnesium is rather a reactive substance as it is high in the reactivity series. When the chemicals react a displacement reaction takes place. The magnesium displaces the hydrogen in the hydrochloric acid
