Abstract:
This report is a description of an experimental determination of the
enthalpy of reaction of sulfuric acid in a reaction with magnesium to
produce magnesium sulfate. Through the use of an ice calorimeter, the
rxn H° D for this reaction is determined to be 1 360kJ mol − − × .
Introduction:
This report details an experiment in thermochemistry. Included are
the methods, results, and interpretation of results of an experimental
determination of an enthalpy of reaction. The reaction being studied is
between sulfuric acid, and magnesium metal.
( ) ( H2SO4 aq +Mg s)®H2 ( g )+MgSO4 (s)
This reaction is run as an isothermal reaction, where the enthalpy
change is measured by the change in volume of melting ice. Published
values for the density of water, and ice, as well as the heat of fusion of
water will be used to determine the amount of heat energy that is released
by the reaction. The relationship between the changing volume of the
calorimeter, and the......
