Which of the following cell diagrams represents a galvanic cell? ($\varepsilon$ $\circ$ _red(Sn²⁺/Sn)= -0.138V,$\varepsilon$ $\circ$ _red(H⁺/H₂)= 0.00 V)

Question

Quizplus · Accepted Answer

In a galvanic cell, the anode is where oxidation occurs and the cathode is where reduction occurs. The cell potential should be positive for spontaneous reactions. Given the standard reduction potentials, Sn to Sn^2+ has a more negative potential (-0.138V) compared to H^+ to H2 (0.00V), meaning Sn will oxidize (lose electrons) and H^+ will reduce (gain electrons). Thus, the correct configuration is Sn(s) at the anode side and H2(g) at the cathode side, which matches option B.
