Q. What is the Electrometallurgy?
The above two metallurgical processes, namely pyrometallurgy and hydrometallurgy can be used in the extraction of a fairly large number of metals. These processes, thus, cannot be used in cases:
In these cases, metals can be extracted by electrolysis of their salts in molten state. Thus, magnesium and sodium are generated by electrolysis of fused chlorides, where the metals re Iiberated at the chlorine and cathode gas is evolved at the anode. Given reactions take place in the mean while electrolysis:
Anode: 2Cl- ---------> Cl2 (g) + 2e
Cathode: 2Na+ 2e ------> 2Na (l)
Mg2+ + 2e---------------> Mg (l)
Number of unpaired electrons in the ground state of beryllium atom is: (1) 2 (2) 1 (3) 0 (4) All the above Ans: 0
Nitrogen atom has an atomic number of 7 and oxygen has an atomic number 8. The total number of electrons in a nitrate ion will be: (1) 8 (2) 16 (3) 32
