Determine E°_cell at 25 °C for the following reaction: 3 Sn²⁺(aq)+ 2 Al(s)→ 2 Al³⁺(aq)+ 3 Sn(s) Al³⁺(aq)+ 3 e^- → Al(s)E° = -1.676 V Sn²⁺(aq)+ 2 e^- → Sn(s)E° = -0.137 V

Quizplus · Accepted Answer

The standard cell potential (E°cell) is calculated using the formula E°cell = E°cathode - E°anode. Here, Sn²⁺/Sn is the cathode with E° = -0.137 V, and Al³⁺/Al is the anode with E° = -1.676 V. Thus, E°cell = -0.137 V - (-1.676 V) = 1.539 V.
