Determining the Stoichiometry
of Chemical Reactions
Learn the method of continuous variation to determine the mole ratio of the reactants
and predict the chemical formula of the product for specific chemical reactions. In
Part 1, the students mix known amounts of iron(III) nitrate and sodium hydroxide in a
series of reactions to form a precipitate. Each reaction contains a different mole ratio
of reactants. The students extrapolate the data to determine the optimum ratio of
reactants and predict the correct formula of the precipitated product. The experiment
is repeated in Part 2 for copper(II) chloride and sodium phosphate.

Kinetics of a Reaction
Students study the kinetics of a clock reaction involving the oxidation of iodide ion
by bromate ion in the presence of an acid. First, students study the effect of concentration
on the rate of reaction to determine the order of reaction for each reactant
and the rate constant. Second, the activation energy is determined by varying the
temperature, measuring the rate and calculating the rate constant at the different
temperatures. Finally the effect of a catalyst on the reaction rate is studied.

Kinetics of a Redox Reaction
Students study the rate of the reaction of FD&C Red Dye #3 with sodium hypochlorite
using a spectrophotometer. First, students create a calibration curve for the dye. Then
they find the order of reaction for each of the reactants by varying the concentration
of each reactant individually. Finally, a graphical analysis of the relationship of
concentration versus time is used to calculate the rate constant. Includes optional
FD&C Blue Dye #1 for better absorbance with some colorimeters.

Thermodynamics—
Enthalpy of Reaction and Hess’s Law
Students verify Hess’s Law in this experiment. Three acid–base reactions, chosen
so that the third reaction equation equals the first reaction minus the second, are
measured for temperature change by calorimetry. The values of heat change and
enthalpy of reaction are calculated for each of the three reactions. The reaction
results are then compared to verify Hess’s Law.

Separation and Qualitative
Determination of Cations and Anions
Students analyze two solution sets of four cations and four anions. For each set, a
specific qualitative scheme is followed to separately detect each of the four ions
present. Students are then given two unknown solution sets to analyze. By following
the qualitative schemes, students determine which cations and anions are present
and which are absent from the two samples. Four to five 50-minute lab sessions will
be needed to complete all four sets of analyses.

Determining the Molar Volume of a Gas
Students determine the volume of one mole of hydrogen gas at standard temperature
and pressure (STP). Hydrogen is generated by the reaction of a known mass
of magnesium with an excess of hydrochloric acid in an inverted gas measuring
tube filled with water. The volume of hydrogen collected by water displacement
is measured and corrected for differences in temperature and pressure in order to
calculate the molar volume of hydrogen at STP.
