A gаlvаnic cell is cоnstructed using In3+(аq)/In(s) (Eоcell=-0.3382V) and Mn2+(aq)/Mn(s) (Eоcell=-1.185V) electrodes in 1.00-molar solutions of their nitrates. 1.00 M solution of KNO3 is used in a salt bridge. Both solutions are at 25o Consider the picture of the voltaic cell. Use the labels (numbers) to answer the questions below (8 pts): identify half-cell where reduction process takes place; identify half-cell where oxidation process takes place; identify solid cathode; identify solid anode; identify the salt bridge; show the direction of the flow of electrons; show the flow of cations; show the flow of anions; Answer the following questions (5+5=10 pts): write the cathode and anode reactions and a balanced net ionic equation for the spontaneous reaction that occurs as the cell operates write a short standard cell notation and calculate the standard cell potential To receive full credit, report your answers below and submit a picture of your work to the Exam 4 Solutions, Extra Credit and Partial Credit assignment AFTER SUBMITTING COMPLETED Midterm.
