Classic AP Requirement #21—Measurements Using Electrochemical Cells and Electroplating

A microscale series of half-cells is constructed by placing a piece of metal into a solution of the metal’s ions. The half-cells are connected by a salt bridge, and the reduction potential of each cell is measured. Students then construct a table of reduction potentials and apply the Nernst equation through further experimentation.

Students learn how to use a voltmeter, determine the anode and cathode of a cell and calculate net ionic equations.

Complete for 24 students working in pairs.

Performance Expectations

HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
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.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
HS-PS2-6. Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
