Electrochemistry

In the original version of the Daniell cell a porous cup containing sulfuric acid and a zinc electrode is placed in a copper container filled with 1.0 M copper(II) sulfate solution.

Select various metals to test in aqueous M2+ solutions. Build an activity series of metals based upon observations of whether or not a metal reacts with a M2+ aqueous solution. Option to view a computer animation at the particle level of the interaction of the M2+ ion with the metal electrode. Based on observations, write the the oxidation-reduction half-reactions. In this activity, students will run simulated tests of various metals in aqueous solutions to determine the relative reactivity of these metals. A total of eight metals will be observed in various combinations with the corresponding metal nitrate solutions and hydrochloric acid. Students will interpret the data collected to construct an activity series of the elements used in this simulation (AACT, 2021).

Voltaic Cell: Cu/Cu concentration cell

Electrochemical Cells Computer Simulaiton Voltaic Cells Concentration Cells Nernst Cell

Electrolytic Cell: two copper electrodes in 1.0 M CuSO4(aq) are connected to a D.C. Power Supply. When current is applied to the electrolysis cell copper(II) ions are reduced to copper atoms at the cathode and copper atoms are oxidized to copper(II) ions at the anode. The time to plate the metal is recorded along with the current (amps).
