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)
A hydrocarbon z with molecular mass 78 on combustion gave 3.384g of carbon (IV) oxide and 0.693g of water. Determine the molecular formula of Z and draw its structure. [H=1, C=12,
