Aluminium

Vedclass · Answer

(C) The process of extracting metals from their oxides using aluminium as a reducing agent is known as the thermite reaction or aluminothermic process.In this process, highly reactive metals like aluminium are used to reduce the oxides of less reactive metals such as chromium $(Cr_2O_3)$ and manganese $(MnO_2)$.The reaction is highly exothermic, releasing a large amount of heat, which melts the metal produced.For example: $Cr_2O_3 + 2Al ightarrow 2Cr + Al_2O_3 + 	ext{Heat}$.

Which substance is used for the chemical reduction of metal oxides like chromium and manganese to obtain the metal?
