Vedclass · Answer

(D) $1$. Electrolysis of aqueous $NaCl$ (brine) produces $Cl_2$ gas at the anode: $2Cl^- \rightarrow Cl_2 + 2e^-$.$2$. Oxidation of conc. $HCl$ by $KMnO_4$ produces $Cl_2$ gas: $2KMnO_4 + 16HCl \rightarrow 2KCl + 2MnCl_2 + 8H_2O + 5Cl_2$.$3$. Oxidation of conc. $HCl$ by $MnO_2$ produces $Cl_2$ gas: $MnO_2 + 4HCl \rightarrow MnCl_2 + 2H_2O + Cl_2$.$4$. The reaction between $NaCl$ and conc. $H_2SO_4$ produces $HCl$ gas,not $Cl_2$ gas: $NaCl + H_2SO_4 \rightarrow NaHSO_4 + HCl$.

Which of the following processes cannot produce $Cl_2$ gas?
