In the pidgeon process, Mg is produced by:
Correct answer: B. Reducing calcined dolomite with ferrosilicon at high temperature under pressure.
- A. Electrolysis of fused MgCl2
- B. Reducing calcined dolomite with ferrosilicon at high temperature under pressure.
- C. Both are correct
- D. None is correct
Explanation
In the Pidgeon process, magnesium is produced by reducing calcined dolomite with ferrosilicon at high temperature under pressure. The MgO obtained from MgCO3 is combined with Fe/Si to create Mg vapors, which are then condensed to obtain Mg metal. The other options are incorrect because they do not accurately describe the process involved in producing magnesium through the Pidgeon process.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
