Chemistry - Metallurgy Question with Solution | TestHub

Method of extraction of metals from their ores depends on the type of metal. While the less reactive can be extracted through pyrometallurgy, more reactive may require electro-reduction. One such method is Down’s process for extracting Mg which uses molten mixture of 35% anhydrous MgCl₂ , 50% NaCl and 15% CaCl₂ as electrolyte. Based on this info answer the question that follow.
