How is Bauxite purified by Serpeck's process? Video Explanation Answer Finely powdered bauxite (Al2 O3 )is heated with coke and N2 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.

Serpeck's process is the process of converting bauxite into aluminum nitride. This process is generally used when silica is present in the bauxite ore. Therefore, Hall's process, Baeyer's process and Serpeck's process are the various processes used for the purification of bauxite. Hence, options A,B and C are correct. Separation ...

Serpeck's process: This process is used when silica is present in considerable amount of bauxide ore. I couldn't find any information on the efficiency, but I suspect both are efficient in their own way. We cannot compare these two processes as they are used for two different impurities.

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.
