Please do part C and D
3. Magnesium is produced at MagCorp (located near the Great Salt Lake) using electrolysis. The salt water is evaporated to recover MgCl2, which is electrochemically reduced to Mg. One half cell reaction, written as a reduction reaction is: Clg 2e 2Cl with a Vo value of 1.3583V (a) Give the other half-cell reaction, write the overall reaction, and calculate AV for the overall reaction (b) Write the equilibrium constant using partial pressures, concentrations, and/or activities. (c) The MgCl2 (density 2.32g/cc) that reacts is 12.5 wt% of a molten salt solution with 87.5 wt% being other chlorides Naci, KCl, LiCl) that do not enter into the reaction, but have a combined density of 2.11g/cc. Calculate the molar concentrations of the magnesium and the chlorine ions in the nonaqueous salt bath. d) The partial pressure of chlorine gas is one atmosphere as it evolves at one of the electrodes. Calculate the minimum voltage necessary to drive overall reaction if it occurs at state any assumptions you made
