Which of the following process is used in the extractive metallurgy of magnesium ?A. Fused salt electrolysisB. Self reductionC. Aqueous solution electrolysisD. Thermite process |
|
Answer» Correct Answer - 1 From salts of magnesium, magnesium can not be extracted by other chemical methods as magnesium itself acts as a reducing agent and Mg obtained at cathode during electrolyte of its salt solution, reacts with water forming `Mg(OH)_(2)` . `MgCl_(2)hArr Mg^(2+)+2Cl^(-),"At cathode"Mg^(2+)+2e^(-)rarrMg,"At anode"2Cl^(-)rarrCl_(2)+2e^(-)` |
