Product Details

Big Ideas 1 and 3. Transition metals are well known to form colored compounds. Using spectroscopic methods, the concentrations of these complexes in solution can be determined. In this time-saving lab, students systematically vary the concentration of the reactants in order to determine the reaction stoichiometry. A prelab homework assignment introduces the ideas and concepts needed to succeed on lab day. Complete for 24 students working in pairs.

Performance Expectations

HS-PS1-4: Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
HS-PS1-5: Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-PS1-6: Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
