Question
8. For the chemical reaction $2AgCl(s) + H_2(g) \rightarrow 2HCl(aq) + 2Ag(s)$, which of the following is the correct IUPAC cell representation?
Answer: C
💡 Solution & Explanation
Anode: $H_2 \rightarrow 2H^+ + 2e^-$. Cathode: $2AgCl + 2e^- \rightarrow 2Ag + 2Cl^-$. The $H^+$ and $Cl^-$ are in the same phase (aqueous HCl). No salt bridge is needed. Representation: Pt / H2 / HCl(aq) / AgCl(s) / Ag.
