Vedclass · Answer

(C) The preparation of $Cl_2$ gas from concentrated $HCl$ at room temperature is achieved by using strong oxidizing agents like $KMnO_4$.The chemical reaction is: $2KMnO_4 + 16HCl \rightarrow 2KCl + 2MnCl_2 + 8H_2O + 5Cl_2$.While $MnO_2$ also oxidizes $HCl$ to $Cl_2$, it typically requires heating, whereas $KMnO_4$ can perform this reaction at room temperature.
