8. For the chemical reaction , which of the following is the correct IUPAC cell representation? — Electrochemistry Chemistry Question

💡 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.
