Question

Using tabulated standard reduction potentials from your text, calculate the standard cell potential, Eºcell (always positive for a galvanic cell), based on the following reaction: Cu2+(aq) + Mg(s) = Mg2+ (aq) + Cu(s) Eºcell = cf Table A5.5, p A24 Zumdahl "Chemical Principles" 8th ed. 1pts Submit Answer Tries 0/5 A galvanic cell based on the above reaction is constructed according to the generic sketch of a galvanic cell shown below: Choose the label which best describes the following: Solution containing Cu2+ Electrode at which reduction of copper ions occurs The overall, balanced, spontaneous reaction occurring in this (standard) cell is: 2Cu+ (aq) + Mg(s) + Mg2+(aq) + 2Cu(s) Mg2+(aq) + Cu(s) + Cu2+(aq) + Mg(s) 2Cu2+ (aq) + Mg(s) + Mg2+ (aq) + 2Cut(aq) Cu2+ (aq) + Mg(s) - Mg2+ (aq) + Cu(s) The salt bridge completes the electrical circuit while separating the anode and cathode compartments. The salt bridge is labeled 'D'. The solution in tube 'D' must contain an electrolyte for the cell to operate. The salt bridge is intended to prevent counter ions from flowing between the two cell compartments. Tube 'D' allows Cu2+ ions to migrate readily to the other compartment and to react directly with the Mg electrode. 1pts
