Determine the Reaction Stoichiometry and the Valency of Magnesium

Objective: To study the quantitative relationship between the amount of the reactants and products of a reaction. A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium. Introduction: Stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction. Stoichiometry can be used to calculate the amounts of products with given the reactants and percent yield. In this…

Determination of Iron by Reaction with Permanganate a Redox Titration

The purpose of this experiment was to find the percentage of iron in an unknown iron oxide sample which could be determined through titration with a standard solution of potassium permanganate. Success in this analysis requires careful preparation and attention to detail. Performing this experiment also provides practice at titrations. The overall reaction is: 8H+(aq) + MnO4-(aq) + 5e- ┬áMn2+(aq) + 4H2O Theory: In acid solutions the permanganate ion undergoes reduction to manganese (2+) ion. Since the permanganate ion is…

Hydrogen Vehicles

Introduction There are many debates that are advocating for a proper implementation of transport systems, involving greatly upgraded sea transport, conversion of freight industry away from the road network. It is therefore possible for a company to reduce greenhouse gas for the benefit of the environment, through the adaptation of these transport systems. The debates also advocates for the use of hydrogen fuelled cars. This kind of vehicles use hydrogen gas as their powering tool and is considered the safest…
