The dioxides react with concentrated hydrochloric acid first to give … WebCO 2 and SiO 2 are acidic due to electron deficiency. SnO 2 is amphoteric in nature as it can work as acid as well as base. PbO 2 is an oxidising agent because as move down the group oxidation state II become more stable so Pb II is more stable than Pb IV has due to this reason PbO 2 has tendency to get electron and works as oxidising agent.
