You would like to develop a new galvanic cell and decide to use two very toxic electrode materials, mercury and cadmium. But because they are toxic, you decide to use a low concentration of each material. Cd I Cd²+ (0.20M) 1. The ◆ electrode is the anode, and the 2. Write the two half equations and the balanced overall equation: The half reaction for chromium (hint written as a reduction): The half reaction for mercury (hint written as a reduction): Overall reaction balanced equation is: Eºcell = Ecell = ◆ Has the voltage improved? is the cathode + 3. What is the Eºcell and the Ecell of this reaction? Have you improved your battery by reducing the concentration? Hint: use the Nerst equation E = E° -RT/nF x(InQ) || Hg²+ (0.10M) I Hg
