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)
Q. Show the Effect of concentration on Chemical Equilibrium? Ans. When more of one of the chemicals is added to the reaction, more collisions take place moving the reactio
what is lattice point?
Cavitation occurs when the pressure in localized regions reaches the vapor pressure. This can cause actually cause structural damage if vapor bubbles form and burst. Consider a sys
Viscosity: Viscosity characterizes the motion of fluids in the presence of a mechanical shear force. All fluids can flow, and the resistance they pose to such flow is called VI
