a. For the electrolysis of molten BaCl2, diagram a cell. Include the direction in which a battery would be placed to power the cell. Write out half-reactions. Label flow of electrons, anode, cathode, indicate what is formed at each electrode (assume electrodes are generic metal). Could this reaction be carried out in aqueous solution? Why or why not (justify numerically). b. 0.67 g of Ag is deposited electrolytically from AgNO3after a certain period of time when subjected to a 12A...

Draw out a cell for Al in Al(NO3)3 and Ag in AgNO3. Label the anode and cathode sides, including charge on each electrode. (hint: use a table of standard reduction potentials). Indicate direction of electron flow. Write the net reaction, and the half reactions. What is the standard cell potential? Indicate for both electrodes whether they are dissolving, growing, or staying the same size. Assuming the salt bridge contains KNO3, indicate flow of ions into and out of salt bridge....

In a galvanic cell a spontaneous redox reaction occurs However, the reactants are separated such that the transfer of electrons is forced to occur across a The resulting electricity is measured in volts(V) and is the sum of the potentials of the oxidation and reduction half-reactions: By reversing the reduction half-reactions you get the corresponding oxidation sign of You can also write the equivalent equation in terms of the reduction potentials and avoid manipulating standard potentials A table of standard...

In a galvanic cell, a spontaneous redox reaction occurs. However the reactants are separated such that the transfer of electrons is forced to occur across a wire. The resulting electricity is measured in volts (V) and is the sum of the potentials of the oxidation and reduction half-reactions: E^o cell = E^o red + E^o ox By reversing the reduction half-reactions, you get the corresponding oxidation half-reaction, for which E^o ox has the opposite sign of E^o red You can...
