प्रश्न
\[\ce{MnO2}\], \[\ce{PbO2}\] and red lead react with \[\ce{conc. HCl}\] acid liberates \[\ce{Cl2}\].
What is the common property being shown by these metal oxides?
उत्तर
\[\ce{MnO2}\], red lead \[\ce{(Pb3O4)}\], and \[\ce{PbO2}\] are all powerful oxidizing agents that exhibit a reducing property when reacting with \[\ce{conc. HCl}\] is used to liberate \[\ce{Cl2}\] (gas), and oxidizing chemicals oxidize the \[\ce{conc. HCl}\] converts to chlorine.
