36. Which primary reaction occurs at the anode during the electrolysis of completely anhydrous fused — Electrochemistry Chemistry Question

💡 Solution & Explanation

In molten lead bromide, the only ions present are $Pb^{2+}$ and $Br^-$. At the anode (the site of oxidation), bromide ions lose electrons to form bromine gas: $2Br^- \rightarrow Br_2 + 2e^-$.
