Highly reactive metals with lower reduction potentials than hydrogen are not obtained by electrolysis of aqueous solutions of their salts since their cations cannot be reduced at cathode in presence of water. Of the above metals, Magnesium is the only metal which has reduction potential less than that of Hydrogen. Hence, Option "B" is the correct answer.

Recently I was taught how aluminium is commercially extracted. The ore is first concentrated by leaching either by Bayer's process for red bauxite (impurity: ce{Fe2O3}) or by Serpeck's process for white bauxite (impurity: ce{SiO2}). Then alumina is reduced electrolytically via HallHéroult's process directly to 99% pure aluminium.

How is Bauxite purified by Serpeck's process? Medium Solution Verified by Toppr Finely powdered bauxite (Al 2O 3) is heated with coke and N 2 to 2000 K. Alumina forms aluminium nitride and silica is reduced to Si which is volatile. The hydrolysis of aluminium nitride gives aluminium hydroxide which on heating gives pure alumina.

The metal obtained in the HallHéroult process is about 99% pure, and for most purposes it is taken as pure metal. However, further purification of aluminium can be carried out by the Hoopes process. This is an electrolytic process. Serpeck's Process Bauxite containing high percentage of silica can be purified by Serpeck's process.
